Prerelaxation in quantum, classical, and quantum-classical two-impurity models
Michael Elbracht, Michael Potthoff
We numerically study the relaxation dynamics of impurity-host systems, focusing on the presence of long-lived metastable states in the non-equilibrium dynamics after an initial exc…
Long-time relaxation dynamics of a spin coupled to a Chern insulator
Michael Elbracht, Michael Potthoff
The relaxation of a classical spin, exchange coupled to the local magnetic moment at an edge site of the one-dimensional spinful Su-Schrieffer-Heeger model is studied numerically b…
Accessing long timescales in the relaxation dynamics of spins coupled to a conduction-electron system using absorbing boundary conditions
Michael Elbracht, Michael Potthoff
The relaxation time of a classical spin interacting with a large conduction-electron system is computed for a weak magnetic field, which initially drives the spin out of equilibriu…
Topological spin torque emerging in classical-spin systems with different time scales
Michael Elbracht, Simon Michel, Michael Potthoff
In classical spin systems with two largely different inherent time scales, the configuration of the fast spins almost instantaneously follows the slow-spin dynamics. We develop the…
