Local integrability breaking and exponential localization of leading Lyapunov vectors
Jiaozi Wang, Tomaž Prosen, Giulio Casati
We study integrability breaking and transport in a discrete space-time lattice with a local integrability breaking perturbation. We find a singular distribution of the Lyapunov spe…
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…
Scaling of diffusion constants in perturbed easy-axis Heisenberg spin chains
Markus Kraft, Mariel Kempa, Jiaozi Wang +2
Understanding the physics of the integrable spin-1/2 XXZ chain has witnessed substantial progress, due to the development and application of sophisticated analytical and numerical…
Evidence for simple "arrow of time functions" in closed chaotic quantum systems
Merlin Füllgraf, Jiaozi Wang, Jochen Gemmer
Through an explicit construction, we assign to any infinite temperature autocorrelation function a set of functions . The construction of from requir…
Decoherence of Histories: Chaotic Versus Integrable Systems
Jiaozi Wang, Philipp Strasberg
We study the emergence of decoherent histories in isolated systems based on exact numerical integration of the Schrödinger equation for a Heisenberg chain. We reveal that the natur…
Lindblad quantum dynamics from correlation functions of classical spin chains
Markus Kraft, Mariel Kempa, Jiaozi Wang +1
The Lindblad quantum master equation is one of the central approaches to the physics of open quantum systems. In particular, boundary driving enables the study of transport, where…
Hydrodynamics and the eigenstate thermalization hypothesis
Luca Capizzi, Jiaozi Wang, Xiansong Xu +2
The eigenstate thermalization hypothesis (ETH) describes the properties of diagonal and off-diagonal matrix elements of local operators in the eigenenergy basis. In this work, we p…
