LREI: A fast numerical solver for quantum Landau-Lifshitz equations

Davoud Mirzaei, Behnam Hashemi, Vahid Azimi-Mousolou

We develop LREI (Low-Rank Eigenmode Integration), a memory- and time-efficient scheme for solving quantum Landau-Lifshitz (q-LL) and quantum Landau-Lifshitz-Gilbert (q-LLG) equatio…
