Faster Randomized Dynamical Decoupling
Article | Quantum Information, Science, and Technology | 2026-01-02 05:00 EST
Changhao Yi, Leeseok Kim, and Milad Marvian
We present a randomized dynamical decoupling (DD) protocol that can substantially improve the performance of any given deterministic DD scheme for suppressing coherent noise by using no more than two additional pulses. Our construction is implemented by probabilistically applying sequences of pulses…

Positive Geometry for Stringy Scalar Amplitudes
Article | Particles and Fields | 2026-01-02 05:00 EST

We introduce a new positive geometry, the associahedral grid, which provides a geometric realization of the inverse string theory Kawai-Lewellen-Tye kernel. It captures the full dependence of stringified amplitudes for biadjoint scalar theory, pions in the nonlinear sigma model (NLSM), and the…

Turbulent Multiscale Interactions between Tearing Modes, Trapped-Electron Modes, and Zonal Flows
Article | Plasma and Solar Physics, Accelerators and Beams | 2026-01-02 05:00 EST
T. Jitsuk, M. J. Pueschel, P. W. Terry, and A. Di Siena
Interactions between MHD-scale tearing modes (TMs) and ion-gyroradius-scale trapped-electron modes (TEMs) in a fusion plasma are simulated with global gyrokinetics, using a consistent set of fixed equilibrium profiles. Unstable core TMs nonlinearly couple and transfer energy to smaller-scale stable …

Quantum Vortices Leave a Macroscopic Signature in the Thermal Background
Article | Condensed Matter and Materials | 2026-01-02 05:00 EST
Luca Galantucci, Giorgio Krstulovic, and Carlo F. Barenghi
Recent work has highlighted the remarkable properties of quantum turbulence in superfluid helium II, consisting of a disordered tangle of quantized vortex lines which interact with each other and reconnect when they collide. According to Landau's two-fluid theory, these vortex lines move in a surrou…

Yujie Lan, Yuhao Lei, Congcong Le, Brenden R. Ortiz, Nicholas C. Plumb, Milan Radovic, Xianxin Wu, Ming Shi, Stephen D. Wilson, and Yong Hu
Kagome materials offer a versatile platform for exploring correlated and topological quantum states, where Van Hove singularities (VHSs) play a pivotal role in driving electronic instabilities, exhibiting distinct behaviors depending on electron filling and interaction settings. In the recently disc…

Quantum Chemistry for Solids Made Simple on the Clifford Torus
Article | Condensed Matter and Materials | 2026-01-02 05:00 EST
Amer Alrakik, Gian Luigi Bendazzoli, Stefano Evangelisti, and J. Arjan Berger
We present a general theory to treat periodic solids with quantum-chemistry methods. It relies on two main developments: (1) the modeling of a solid as a Clifford torus, which is a torus that is both periodic and flat, and (2) the introduction of a periodic Gaussian basis set that is compatible with…

Stripe-Nematic Phase of Composite Fermions
Article | Condensed Matter and Materials | 2026-01-02 05:00 EST
Chengyu Wang, S. K. Singh, C. T. Tai, A. Gupta, L. N. Pfeiffer, K. W. Baldwin, and M. Shayegan
Electronic stripe-nematic phases are fascinating, strongly correlated states characterized by spontaneous rotational symmetry breaking. In the quantum Hall regime, such phases typically emerge at half-filled, high-orbital-index () Landau levels (LLs) where the short-range Coulomb interaction is s…

Orbital Inverse Faraday and Cotton-Mouton Effects in Hall Fluids
Article | Condensed Matter and Materials | 2026-01-02 05:00 EST
Gabriel Cardoso, Erlend Syljuåsen, and Alexander V. Balatsky
We report two light-induced orbital magnetization effects in quantum Hall (QH) fluids, stemming from their transverse response. The first is a purely transverse contribution to the inverse Faraday effect (IFE), where circularly polarized light induces a dc magnetization by stirring the charged fluid…

Half-Quantized Chiral Edge Current in a $C=1/2$ Parity Anomaly State

A single massive Dirac surface band is predicted to exhibit a half-quantized Hall conductance, a hallmark of the parity anomaly state in quantum field theory. Experimental signatures of the parity anomaly state have been observed in semimagnetic topological insulator (TI) bilayers, yet w…

Magnets have recently emerged as promising candidates for quantum computing, particularly using topologically-protected nanoscale spin textures. While the quantum dynamics of such spin textures has been theoretically studied, direct experimental evidence of their nonclassical behavior remains an ope…
