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…
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…
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…
Real-time broadening of bath-induced density profiles from closed-system correlation functions
Tjark Heitmann, Jonas Richter, Jacek Herbrych +2
The Lindblad master equation is one of the main approaches to open quantum systems. While it has been widely applied in the context of condensed matter systems to study properties…
Magnetization and energy dynamics in spin ladders: Evidence of diffusion in time, frequency, position, and momentum
Jonas Richter, Fengping Jin, Lars Knipschild +5
The dynamics of magnetization and energy densities are studied in the two-leg spin-1/2 ladder. Using an efficient pure-state approach based on the concept of typicality, we calcula…
Sudden removal of a static force in a disordered system: Induced dynamics, thermalization, and transport
Jonas Richter, Jacek Herbrych, Robin Steinigeweg
We study the real-time dynamics of local occupation numbers in a one-dimensional model of spinless fermions with a random on-site potential for a certain class of initial states. T…
