Approximate Decoherence, Recoherence and Records in Isolated Quantum Systems
Philipp Strasberg, Joseph Schindler, Jiaozi Wang +1
Using the framework of decoherent histories, we study which past events leave detectable records in isolated quantum systems under the realistic assumption that decoherence is appr…
Statistical structural properties of many-body chaotic eigenfunctions and applications
Wen-ge Wang, Qingchen Li, Jiaozi Wang +1
In this paper, we employ a semiperturbative theory to study the statistical structural properties of energy eigenfunctions (EFs) in many-body quantum chaotic systems consisting of…
Ergodicity and hydrodynamics: from quantum to classical spin systems
Jiaozi Wang, Luca Capizzi, Dario Poletti +1
We show that in classical spin systems the precise nature of the late-time hydrodynamic tails of the autocorrelation functions of a generic observable is determined by (i) the dyna…
Lanczos-Pascal approach to correlation functions in chaotic quantum systems
Merlin Füllgraf, Jiaozi Wang, Robin Steinigeweg +1
We suggest a method to compute approximations to temporal correlation functions of few-body observables in chaotic many-body systems in the thermodynamic limit based on the respect…
Scrutinizing the Mori memory function for diffusion in periodic quantum systems
Scott D. Linz, Jiaozi Wang, Robin Steinigeweg +1
Diffusion is an ubiquitous phenomenon. It is a widespread belief that as long as the area under a current autocorrelation function converges in time, the corresponding spatiotempor…
Nontrivial damping of magnetization currents in perturbed spin chains
Mariel Kempa, Markus Kraft, Jiaozi Wang +1
Since perturbations are omnipresent in physics, understanding their impact on the dynamics of quantum many-body systems is a vitally important but notoriously difficult question. O…
