Hydrodynamic tails in chaotic spin chains with quantum group symmetry
Luca V. Delacretaz, Victor Gorbenko, Jiaozi Wang +2
The interplay between symmetry and thermalization governs the late-time dynamics of local quantum and classical many-body systems at nonzero temperature. Recently, two parallel fro…
Resonant level model from a Krylov perspective: Lanczos coefficients in a quadratic model
Merlin Füllgraf, Jiaozi Wang, Jochen Gemmer +1
We study the Lanczos coefficients in a quadratic model given by an impurity interacting with a multi-mode field of fermions, also known as resonant level model. We analytically der…
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…
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…
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…
Estimate of equilibration times of quantum correlation functions in the thermodynamic limit based on Lanczos coefficients
Jiaozi Wang, Merlin Füllgraf, Jochen Gemmer
We study the equilibration times of local observables in quantum chaotic systems by considering their auto-correlation functions. Based on the recursion method, we su…
