Gradient-estimator design overcomes trainability barriers in neural-network-based variational optimization
Yi-Ran Xue, Rui Wang, Baigeng Wang +1
Neural networks provide expressive representations for scientific computing. However, even sufficiently expressive networks can suffer training failure in weak-gradient regimes, li…
Low-variance estimators overcome the phase-gradient bottleneck in complex-valued neural quantum states
Yi-Ran Xue, Rui Wang, Baigeng Wang +1
Complex neural quantum states are difficult to optimize when their wavefunction phase carries gauge, chiral, fermionic, or topological structure. We show that the major failure mod…
Nonequilibrium from Equilibrium: Chiral Current-Carrying States in the Spin-1 Babujian-Takhtajan Chain
Bahar Jafari-Zadeh, Chenan Wei, Hrachya M. Babujian +1
We study the spin- Babujian-Takhtajan chain deformed by its third conserved charge . We derive and show that it is a dimensionless energy current and that its local d…
Higher order Magnus expansions for driven two-level quantum dynamics
Chen Wei, Frank Großmann
We investigate the Magnus expansion for a generic time-dependent two-level system under single-axis driving.By virtue of the su(2) Lie algebra, the expansion is decomposed into a c…
Spontaneous Symmetry Breaking in Chiral Current-Carrying High-Energy Eigenstates
Tigran A. Sedrakyan, Jun-Jun Pang, Chenan Wei +1
Typical finite-energy-density eigenstates of nonintegrable systems are expected to obey the eigenstate thermalization hypothesis and to reproduce thermal local observables. In inte…
Chiral vortex-line liquid of three-dimensional interacting Bose systems with moat dispersion
Bahar Jafari-Zadeh, Chenan Wei, Tigran A. Sedrakyan
We formulate and investigate a novel quantum state, the Chiral Vortex-Line Liquid (CVLL), emerging in three-dimensional interacting Bose systems exhibiting moat-band dispersions. S…
Cavity-Vacuum-Induced Chiral Spin Liquids in Kagome Lattices: Tuning and Probing Topological Quantum Phases via Cavity Quantum Electrodynamics
Chenan Wei, Liu Yang, Qing-Dong Jiang
Topological phases in frustrated quantum magnetic systems have captivated researchers for decades, with the chiral spin liquid (CSL) standing out as one of the most compelling exam…
