Metaheuristic conditional neural network for harvesting skyrmionic metastable states

no code implementations6 Mar 2023 Qichen Xu, I. P. Miranda, Manuel Pereiro, Filipp N. Rybakov, Danny Thonig, Erik Sjöqvist, Pavel Bessarab, Anders Bergman, Olle Eriksson, Pawel Herman, Anna Delin

To demonstrate how this method works, we identify and analyze spin textures with topological charge $Q$ ranging from 1 to $-13$ (where antiskyrmions have $Q<0$) in the Pd/Fe/Ir(111) system, which we model using a classical atomistic spin Hamiltonian based on parameters computed from density functional theory.

Exchange constants for local spin Hamiltonians from tight-binding models

no code implementations8 Mar 2021 Simon Streib, Attila Szilva, Vladislav Borisov, Manuel Pereiro, Anders Bergman, Erik Sjöqvist, Anna Delin, Mikhail I. Katsnelson, Olle Eriksson, Danny Thonig

We consider the mapping of tight-binding electronic structure theory to a local spin Hamiltonian, based on the adiabatic approximation for spin degrees of freedom in itinerant-electron systems.
