Finite-Size Scaling of the Full Eigenstate Thermalization in Quantum Spin Chains
Yuke Zhang, Pengfei Zhang
Despite the unitary evolution of closed quantum systems, long-time expectation of local observables are well described by thermal ensembles, providing the foundation of quantum sta…
Emergent Universality Class in Dissipative Quantum Systems with Dipole Moment Conservation
Wenbo Zhou, Yuke Zhang, Pengfei Zhang
Understanding the non-equilibrium dynamics of quantum many-body systems remains one of the grand challenges of modern physics. In particular, increasing attention has been devoted…
Scrambling Enabled Entropy Accumulation in Open Quantum Systems
Yuke Zhang, Zeyu Liu, Shuo Zhang +2
In closed quantum many-body systems, initially localized information spreads throughout the system and becomes highly complex. This phenomenon, known as information scrambling, is…
Diagnosing Strong-to-Weak Symmetry Breaking via Wightman Correlators
Zeyu Liu, Langxuan Chen, Yuke Zhang +2
Symmetry plays a fundamental role in quantum many-body physics, and a central concept is spontaneous symmetry breaking, which imposes crucial constraints on the possible quantum ph…
