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…
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…
Higher order Magnus expansions for driven two-level quantum dynamics
Chen Wei, Frank GroÃmann
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…
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…
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…
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…
