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…
Theory of Out-of-Time-Ordered Transport
Ruchira Mishra, Jiaozi Wang, Silvia Pappalardi +1
We construct an effective field theory (EFT) that captures the universal behavior of out-of-time-order correlators (OTOCs) at late times in generic quantum many-body systems with c…
Fate of diffusion under integrability breaking of classical integrable magnets
Jiaozi Wang, Sourav Nandy, Markus Kraft +2
Diffusive transport is a ubiquitous phenomenon, yet the microscopic origin of diffusion in interacting physical systems remains a challenging question, irrespective of whether quan…
Scaling of free cumulants in closed system-bath setups
Merlin Füllgraf, Jochen Gemmer, Jiaozi Wang
The Eigenstate Thermalization Hypothesis (ETH) has been established as a cornerstone for understanding thermalization in quantum many-body systems. Recently, there has been growing…
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…
Boundary-driven magnetization transport in the spin- XXZ chain: Role of the system-bath coupling strength and timescales
Mariel Kempa, Markus Kraft, Sourav Nandy +4
Understanding the transport properties of quantum many-body systems is a central challenge in condensed matter and statistical physics. Theoretical studies usually rely on two main…
Eigenstate Thermalization Hypothesis and Random Matrix Theory Universality in Few-Body Systems
Jiaozi Wang, Hua Yan, Robin Steinigeweg +1
In this paper, we study the Feingold-Peres model as an example, which is a well-known paradigm of quantum chaos. Using semiclassical analysis and numerical simulations, we study th…
Eigenstate Thermalization Hypothesis correlations via non-linear Hydrodynamics
Jiaozi Wang, Ruchira Mishra, Tian-Hua Yang +2
The thermalizing dynamics of many-body systems is often described through the lens of the Eigenstate Thermalization Hypothesis (ETH). ETH postulates that the statistical properties…
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…
