Exact Hilbert-space ergodicity from continuous monitoring
Yue Wu, Yuzhi Tong, Liang Mao +1
Quantum evolution is generally expected to drive a quantum many-body system toward equilibrium. This expectation is often justified by the Hilbert-space ergodicity of generic quant…

Enhancing Many-Body Chaos via Entropy Injection from Environment
Yuke Zhang, Wenbo Zhou, Pengfei Zhang
In closed quantum systems, local information spreads throughout the entire system and becomes highly complex under unitary evolution. In contrast, when the system is embedded in an…

Exact Relation Between Wehrl-Rényi Entropy and Many-Body Entanglement
Pengfei Zhang, Chen Xu, Peng Zhang
Quantum entanglement is key to understanding correlations and emergent phenomena in quantum many-body systems. For qubits (distinguishable spin- particles) in a pure quant…
