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.…
Ground-state selection via nonlinear quantum dissipation
Alireza Ataei, Olle Eriksson, Vahid Azimi Mousolou
Finding the ground state of complex quantum systems remains a central challenge in many-body physics, quantum chemistry, and combinatorial optimization, due to the exponential grow…
Magnon Shake-up: Entanglement Generation and Sensing
Vahid Azimi-Mousolou, Anna Delin, Erik Sjöqvist +1
Shake-up phenomena, rooted in the sudden approximation and many-body quantum dynamics, unveil critical characteristics of quantum systems, with wide-ranging applications in molecul…
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…
Quantum spin systems: toroidal classification and geometric duality
Vahid Azimi-Mousolou, Anders Bergman, Anna Delin +4
Toroidal classification and geometric duality in quantum spin systems is presented. Through our classification and duality, we reveal that various bipartite quantum features in mag…
