Nonlinear quantum multi-spin dynamics without entanglement
Ivan P. Miranda, Erik Sjöqvist
We introduce a distinct route for extending classical atomistic spin dynamics into the quantum regime for arbitrary spin , based on a variational product-state \textit{ansatz} t…

Quantum analog of Landau-Lifshitz-Gilbert dynamics
Yuefei Liu, Ivan P. Miranda, Lee Johnson +7
The Landau-Lifshitz-Gilbert (LLG) and Landau-Lifshitz (LL) equations play an essential role for describing the dynamics of magnetization in solids. While a quantum analog of the LL…
