Hamiltonian non-Hermicity: accurate dynamics with the multiple Davydov D Ansätze
L. Zhang, K. Shen, Y. Yan +3
We examine the applicability of the numerically accurate method of time dependent variation with multiple Davydov Ansatze (mDA) to non-Hermitian systems. Three systems of interest…

Dissipative Landau-Zener transitions in a three-level bow-tie model: accurate dynamics with the Davydov multi-D2 Ansatz
Lixing Zhang, Maxim F. Gelin, Yang Zhao
We investigate Landau-Zener (LZ) transitions in the three-level bow-tie model (3L-BTM) in a dissipative environment by using the numerically accurate method of multiple Davydov D2…
