High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, which has been demonstrated using continuous-variable states in microwave cavities or the motional modes of trapped ions. For example, high-dimensional systems can be used to realize ‘Schrödinger cat' states, which are superpositions of widely displaced coherent states that can be used to illustrate quantum effects at large scales. Recent proposals have suggested encoding qubits in high-spin atomic nuclei, which are finite-dimensional systems that can host hardware-efficient versions of continuous-variable codes. Here we demonstrate the creation and manipulation of Schrödinger cat states using the spin-7/2 nucleus of an antimony atom embedded in a silicon nanoelectronic device. We use a multi-frequency control scheme to produce spin rotations that preserve the symmetry of the qudit, and we constitute logical Pauli operations for qubits encoded in the Schrödinger cat states. Our work demonstrates the ability to prepare and control non-classical resource states, which is a prerequisite for applications in quantum information processing and quantum error correction, using our scalable, manufacturable semiconductor platform.

Observation of Joule-Thomson photon-gas expansion

In recent years, a self-consistent optical thermodynamic framework has emerged that offers a systematic methodology to understand, harness and exploit the complex collective dynamics of multimode nonlinear systems. These developments now allow consideration of a series of long-standing problems in optics, including the prospect of funnelling the entire power flowing in a multimode system into its ground state, for which no methodology currently exists. Here we demonstrate an all-optical Joule-Thomson expansion process mediated by photon-photon interactions whereby the temperature of the optical gas drops abruptly to zero. Our experiments in various configurations of coupled multicore nonlinear waveguide arrangements illustrate how light undergoing expansion-induced cooling can be channelled from arbitrary input states into the fundamental mode with near-unity efficiency. We show that the stability of the post-expansion state is ensured through an irreversible process of energy conversion. The all-optical thermodynamic phenomena explored in this study may enable innovative techniques where various uncorrelated but identical sources are merged into a unified spatially coherent state, offering a route for direct beam combining.

Thermal Area Law in Long-Range Interacting Systems

Research article | Mathematical physics | 2025-01-14 05:00 EST

Donghoon Kim, Tomotaka Kuwahara, and Keiji Saito

The area law of the bipartite information measure characterizes one of the most fundamental aspects of quantum many-body physics. In thermal equilibrium, the area law for the mutual information universally holds at arbitrary temperatures as long as the systems have short-range interactions. In systems with power-law decaying interactions, (: distance), conditions for the thermal area law are elusive. In this Letter, we aim to clarify the optimal condition such that the thermal area law universally holds. A standard approach to considering the conditions is to focus on the magnitude of the boundary interaction between two subsystems. However, we find here that the thermal area law is more robust than this conventional argument suggests. We show the optimal threshold for the thermal area law by (: the spatial dimension of the lattice), assuming a power-law decay of the clustering for the bipartite correlations. Remarkably, this condition encompasses even the thermodynamically unstable regimes . We verify this condition numerically, finding that it is qualitatively accurate for both integrable and nonintegrable systems. Unconditional proof of the thermal area law is possible by developing the power-law clustering theorem for above a threshold temperature. Furthermore, the numerical calculation for the logarithmic negativity shows that the same criterion applies to the thermal area law for quantum entanglement.

Quantized Axial Charge of Staggered Fermions and the Chiral Anomaly

Research article | Anomalies | 2025-01-14 05:00 EST

Arkya Chatterjee, Salvatore D. Pace, and Shu-Heng Shao

In the ultralocal lattice Hamiltonian for staggered fermions with a finite-dimensional Hilbert space, there are two conserved, integer-valued charges that flow in the continuum limit to the vector and axial charges of a massless Dirac fermion with a perturbative anomaly. Each of the two lattice charges generates an ordinary U(1) global symmetry that acts locally on operators and can be gauged individually. Interestingly, they do not commute on a finite lattice and generate the Onsager algebra, but their commutator goes to zero in the continuum limit. The chiral anomaly is matched by this non-Abelian algebra, which is consistent with the Nielsen-Ninomiya theorem. We further prove that the presence of these two conserved lattice charges forces the low-energy phase to be gapless, reminiscent of the consequence from perturbative anomalies of continuous global symmetries in continuum field theory. Upon bosonization, these two charges lead to two exact U(1) symmetries in the XX model that flow to the momentum and winding symmetries in the free boson conformal field theory.

Distinguishing Dirac from Majorana Heavy Neutrino at Future Lepton Colliders

Qing-Hong Cao, Kun Cheng, and Yandong Liu

We propose to identify whether a sterile neutrino is Dirac-type or Majorana-type by counting the peak of the rapidity distribution at lepton colliders. Our method requires only one charged-lepton tagging, and the nature of sterile neutrinos can be pinned down once they are confirmed.

We report new results from the neutrino elastic scattering observation with NaI (NEON) experiment in the search for light dark matter (LDM) using of NaI(Tl) exposure. The experiment employs an array of NaI(Tl) crystals with a total mass of 16.7 kg, located 23.7 m away from a 2.8 GW thermal power nuclear reactor. We investigated LDM produced by the invisible decay of dark photons, a well-motivated mechanism generated by high-flux photons during reactor operation. The energy spectra collected during reactor-on and reactor-off periods were compared within the LDM signal region of 1--10 keV. No signal consistent with LDM interaction with electrons was observed, allowing us to set 90% confidence level exclusion limits on the dark matter-electron scattering cross section () across dark matter masses ranging from 1 to . Our results set a 90% confidence level upper limit of for a dark matter mass of , marking the best laboratory result in this mass range. Additionally, our search extends the coverage of LDM below for the first time, assuming the specific invisible decay of dark photons.

Deciphering Hypertriton and Antihypertriton Spins from Their Global Polarizations in Heavy-Ion Collisions

Research article | Particle & resonance production | 2025-01-14 05:00 EST

Understanding the properties of hypernuclei is crucial for constraining the nature of hyperon-nucleon () interactions, which plays a key role in determining the inner structure of compact stars. The lightest hypernuclei and antihypernuclei are the hypertriton (), which consists of a pair of nucleons and a hyperon, and its antinucleus (). Significant knowledge has recently been acquired regarding the mass, lifetime, and binding energy of . However, its exact spin, whether or , remains undetermined in both experimental and theoretical studies. Here, we present a novel method of using the hypertriton global polarization in heavy-ion collisions to decipher not only its total spin but also its internal spin structure. This method is based on the finding that its three different spin structures exhibit distinct beam energy dependence of its global polarization when it is produced in these collisions from the coalescence of proton, neutron and . Future observations of the hypertriton and antihypertriton global polarizations thus provide the opportunity to unveil the spin structures of hypertriton and antihypertriton and their production mechanisms in heavy-ion collisions.

First Identification of Excited States in and Implications for Isospin Nonconserving Forces in Nuclei

Research article | Double beta decay | 2025-01-14 05:00 EST

G. L. Zimba et al.

At a fundamental level, the interactions between protons and protons, protons and neutrons, and neutrons and neutrons are not identical. Such isospin nonconserving interactions emerge when comparing the excitation energy of analog states in triplet nuclei. Here, we extend such an analysis to the , triplet system---the heaviest system for which such complete data exists---and find strong disagreement with contemporary theory. This was achieved by pioneering the technique of recoil-$$ tagging to identify excited states in . We also established a half-life of and extended the band in to .

Observation of Relaxation Stages in a Nonequilibrium Closed Quantum System: Decaying Turbulence in a Trapped Superfluid

Research article | Cold atoms & matter waves | 2025-01-14 05:00 EST

M. A. Moreno-Armijos, A. R. Fritsch, A. D. García-Orozco, S. Sab, G. Telles, Y. Zhu, L. Madeira, S. Nazarenko, V. I. Yukalov, and V. S. Bagnato

The dynamics of nonequilibrium closed quantum systems and their route to thermalization are of fundamental interest to several fields, from cosmology to particle physics. However, a comprehensive description of nonequilibrium phenomena still presents a significant challenge. In this work, we report the observation of distinct stages during the relaxation of the decaying turbulence in trapped Bose-Einstein condensates. Our findings show a direct particle cascade from low to high momenta, a consequence of the energy injection in the system, exhibiting a characteristic universal scaling. This stage is followed by an inverse particle cascade responsible for repopulating the previously depleted condensate. Both cascades can be explained through self-similar solutions provided by wave turbulence theory. These findings provide important insights into the relaxation stages of out-of-equilibrium quantum many-body systems.

Quantum State Transfer via a Multimode Resonator

Research article | Cavity quantum electrodynamics | 2025-01-14 05:00 EST

Yang He and Yu-Xiang Zhang

Large-scale fault-tolerant superconducting quantum computation needs rapid quantum communication to network qubits fabricated on different chips and long-range couplers to implement efficient quantum error correction codes. Quantum channels used for these purposes are best modeled by multimode resonators, which lie between single-mode cavities and waveguides with a continuum of modes. In this Letter, we propose a non-Markovian formalism for quantum state transfer using coupling strengths comparable to the channel's free spectral range (). Our scheme merges features of both the stimulated-Raman-adiabatic-passage-based methods for single-mode cavities and the pitch-and-catch protocol for long waveguides, integrating their advantages of low loss and high speed. It is immune to thermal channel occupations if using harmonic resonators for the sender and receiver.

Metasurface Polarization Optics: Phase Manipulation for Arbitrary Polarization Conversion Condition

Research article | Metasurfaces | 2025-01-14 05:00 EST

Siqi Li, Chen Chen, Guoxi Wang, Suyang Ge, Jiaqi Zhao, Xianshun Ming, Wei Zhao, Tao Li, and Wenfu Zhang

Metasurface polarization optics have attracted considerable attention due to their ability to manipulate independently the wave fronts of different polarization channels with subwavelength scale. Previous methods mainly focused on the condition of complete polarization conversion, restricting the application range of metasurface polarization multiplexing. Here, we proposed a generalized framework of phase manipulation for the metasurface polarization optics, which can realize independent phase control and arbitrary energy distribution of different polarization channels for the arbitrary polarization conversion efficiency. Based on this principle, we experimentally demonstrate tripolarization-channel wave-front control for the arbitrary polarization state (elliptical, circular, and linear). The arbitrary energy distribution of different polarization channels has been achieved via varying the polarization conversion efficiency. The proposed framework significantly improves the performance of metasurface in the polarization multiplexing and energy distribution, and expands the application scope of metasurface in the polarization optics.

All-Optical Blast-Wave Control of Laser Wakefield Acceleration in a Near-Critical Plasma

We propose a novel method for changing the length of laser wakefield electron acceleration in a gas jet using a cylindrical blast-wave created by a perpendicularly focused nanosecond laser pulse. The shock front modifies the wake significantly and stops interaction between the laser pulse and accelerated electron bunch, allowing one to directly control the interaction length and avoid dephasing. It also improves the electron beam quality through the plasma lensing effect between the two shock fronts. We demonstrated both experimentally and numerically how this approach can be used to form a quasimonoenergetic electron bunch with controlled energy and improved divergence as well as tracking changes in the bunch parameters during acceleration.

Nonlinear Superconducting Magnetoelectric Effect

Research article | Magnetoelectric effect | 2025-01-14 05:00 EST

Jin-Xin Hu, Oles Matsyshyn, and Justin C. W. Song

Supercurrent flow can induce a nonvanishing spin magnetization in noncentrosymmetric superconductors with spin-orbit interaction. Often known as the nondissipative magnetoelectric effect, these are most commonly found at linear order in supercurrent flow. Here, we propose that a nonlinear superconducting magnetoelectric (NSM) effect can naturally manifest in magnet-superconductor heterostructures. In such platforms, NSM manifests as the spin polarization generated as a second-order response to a driving supercurrent. Strikingly, we find NSM survives centrosymmetry and is the leading-order magnetic response in a variety of magnetic materials that include both collinear magnets (e.g., -wave planar altermagnet thin film-superconductor) as well as noncollinear magnets (e.g., kagome-superconductor systems). This renders NSM a powerful electric and nondissipative means of controlling magnetization in magnet-superconductor heterostructures, a promising platform for superconducting spintronics.

Hydrodynamic description of collective electron motion turns out to be fruitful, since it provides a reliable physical concept that allows engineering the electron-electron interaction. We experimentally study the relation between two fundamental quantities---the electron viscosity and the Fermi quasiparticle lifetime---beyond the applicability limit of the Fermi liquid theory. We use point contact (PC) geometry to study electron transport and observe superballistic PC conductance, which is a signature of the electron viscosity. At high enough temperatures, the viscosity-lifetime relation is shown to diverge from the theoretically predicted one and turns out to be nontrivial. In addition, we study these phenomena in PCs freely suspended over a substrate, i.e., under the unique experimental conditions of enhanced electron-electron interaction. Suspension is found to reduce the electron viscosity in the whole temperature range, which makes the suspended structures a promising test bed for studying hydrodynamic effects in solids.

Fermionic Isometric Tensor Network States in Two Dimensions

Research article | 2-dimensional systems | 2025-01-14 05:00 EST

Zhehao Dai, Yantao Wu, Taige Wang, and Michael P. Zaletel

We generalize isometric tensor network states to fermionic systems, paving the way for efficient adaptations of 1D tensor network algorithms to 2D fermionic systems. As the first application of this formalism, we developed and benchmarked a time-evolving block-decimation (TEBD) algorithm for real-time and imaginary-time evolution. The imaginary-time evolution produces ground-state energies for gapped systems, systems with a Dirac point, and systems with gapless edge modes to good accuracy. The real-time TEBD captures the scattering of two fermions and the chiral edge dynamics on the boundary of a Chern insulator.

Anomalous Spin and Orbital Hall Phenomena in Antiferromagnetic Systems

J. E. Abrão, E. Santos, J. L. Costa, J. G. S. Santos, J. B. S. Mendes, and A. Azevedo

We investigate anomalous spin and orbital Hall phenomena in antiferromagnetic materials via orbital pumping experiments. Conducting spin and orbital pumping experiments on heterostructures, we unexpectedly observe strong spin and orbital anomalous signals in an out-of-plane configuration. We report a sevenfold increase in the signal of the anomalous inverse orbital Hall effect compared to conventional effects. Our study suggests expanding the orbital Hall angle () to a rank 3 tensor, akin to the spin Hall angle (), to explain the anomalous inverse orbital Hall effect. This work pioneers converting spin-orbital currents into charge currents, advancing the spin-orbitronics domain in antiferromagnetic materials.

We investigate spin relaxation dynamics of interlayer excitons in a heterostructure induced by the Rashba effect. In such a system, Rashba interactions arise from an out-of-plane electric field due to photogenerated interlayer excitons inducing a phonon-assisted intravalley spin relaxation. We develop a theoretical description based on a microscopic approach to quantify the magnitude of Rashba interactions and test these predictions via time-resolved Kerr rotation measurements. In agreement with the calculations, we find that the Rashba-induced intravalley spin mixing becomes the dominating spin relaxation channel above . Our work identifies a previously unexplored spin-depolarization channel in heterostructures which can be used for ultrafast spin manipulation.

Strategy for Direct Detection of Chiral Phonons with Phase-Structured Free Electrons

Research article | Chirality | 2025-01-14 05:00 EST

Marc R. Bourgeois, Andrew W. Rossi, and David J. Masiello

Chiral phonons possessing valley pseudoangular momentum (PAM) underlie a diversity of quantum phenomena of fundamental and applied importance, but are challenging to probe directly. We show that deficiencies of typical momentum-resolved electron energy loss measurements that make it impossible to distinguish the PAM of chiral phonons can be overcome by introducing pinwheel free electron states with well-defined PAM. Transitions between such states generate 2D periodic arrays of in-plane field vortices with polarization textures tailored to selectively couple to desired chiral mode symmetries.

Observation of Nonreciprocal Diffraction of Surface Acoustic Wave

Research article | Magnetoelastic effect | 2025-01-14 05:00 EST

Y. Nii, K. Yamamoto, M. Kanno, S. Maekawa, and Y. Onose

The rectification phenomenon caused by the simultaneous breaking of time-reversal and spatial inversion symmetries has been extended to a wide range of (quasi)particles and waves; however, nonreciprocal diffraction, which is the imbalance of upward and downward deflections, was previously observed only for photons and remained to be extended to other (quasi)particles. In this Letter, we present evidence of the nonreciprocal diffraction of a surface acoustic wave (SAW) utilizing a magnetoelastic grating on a SAW device. Asymmetric diffraction intensities were observed when the ferromagnetic resonance was acoustically excited. Based on a theoretical model, we attribute the microscopic origin of this phenomenon to the resonant scattering involving ferromagnetic resonance excitations. The novel property may pave an avenue to further development of SAW devices for various purposes, including microwave communications and quantum engineering applications.
