Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs
A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. To get a time-linear scaling, we present an approximation to the collision integral, which offers a good tr
