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…
Entanglement Growth from Structured Initial States in Many-Body Localized Systems
Chen Xu, Pengfei Zhang
Understanding how complex entanglement structures emerge is a central problem in quantum many-body physics. Recent work by Zhang et al. has considered structured initial states pre…
Bridging Krylov Complexity and Universal Analog Quantum Simulator
Shuo Zhang, Yuzhi Tong, Pengfei Zhang +1
Quantum simulation of complex many-body systems beyond classical computational capabilities provides a promising route toward understanding novel quantum phases and their transitio…
The Kubo-Thermalization Correspondence
Songtao Huang, Xingyu Li, Jianyi Chen +5
Quantum thermalization describes how interacting quantum systems relax toward thermal equilibrium, a central problem in modern physics. Yet most experimental information on many-bo…
Error-resilient Reversal of Quantum Chaotic Dynamics Enabled by Scramblons
Yu-Chen Li, Tian-Gang Zhou, Shengyu Zhang +8
The emergence of the arrow of time in quantum many-body systems stems from the inherent tendency of Hamiltonian evolution to scramble quantum information and increase entanglement.…
