Lindblad dynamics from spatio-temporal correlation functions in nonintegrable spin-1/2 chains with different boundary conditions
Markus Kraft, Jonas Richter, Fengping Jin +6
We investigate the Lindblad equation in the context of boundary-driven magnetization transport in spin- chains. Our central question is whether the nonequilibrium steady state…
Diffusion constants from the recursion method
Jiaozi Wang, Mats H. Lamann, Robin Steinigeweg +1
Understanding the transport behavior of quantum many-body systems constitutes an important physical endeavor, both experimentally and theoretically. While a reliable classification…
Emergence of unitary symmetry of microcanonically truncated operators in chaotic quantum systems
Jiaozi Wang, Jonas Richter, Mats H. Lamann +3
We study statistical properties of matrix elements of observables written in the energy eigenbasis and truncated to small microcanonical windows. We present numerical evidence indi…
Estimation of equilibration time scales from nested fraction approximations
Christian Bartsch, Anatoly Dymarsky, Mats H. Lamann +3
We consider an autocorrelation function of a quantum mechanical system through the lens of the so-called recursive method, by iteratively evaluating Lanczos coefficients, or solvin…
Interplay of decoherence and relaxation in a two-level system interacting with an infinite-temperature reservoir
Jiaozi Wang, Jochen Gemmer
We study the time evolution of a single qubit in contact with a bath, within the framework of projection operator methods. Employing the so-called modified Redfield theory which al…
Spin-1/2 XXZ chain coupled to two Lindblad baths: Constructing nonequilibrium steady states from equilibrium correlation functions
Tjark Heitmann, Jonas Richter, Fengping Jin +7
State-of-the-art approaches to extract transport coefficients of many-body quantum systems broadly fall into two categories: (i) they target the linear-response regime in terms of…
