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…

Ferroelectrical Switching as a Probe of Quantum Damping in Magnetic Spin Systems
Yuefei Liu, Anna Delin, Olle Eriksson +3
While damped spin dynamics is important for the understanding of magnetic materials, clear signatures of \emph{quantum corrections} to the Gilbert damping mechanism remain elusive.…
