Quantifying non-Markovianity in magnetization dynamics via entropy production rates

Felix Hartmann, Finja Tietjen, R. Matthias Geilhufe +1

Magnetization dynamics is commonly described by the stochastic Landau-Lifshitz-Gilbert (LLG) equation. On picosecond timescales, inertial and open-system extensions of the LLG equa…
