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…
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…
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…
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…
Weak universality, quantum many-body scars and anomalous infinite-temperature autocorrelations in a one-dimensional spin model with duality
Adithi Udupa, Samudra Sur, Sourav Nandy +2
We study a one-dimensional spin- model with three-spin interactions and a transverse magnetic field . The model has a symmetry, and a duality between a…
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…
