A Davydov Ansatz approach to accurate system-bath dynamics in the presence of multiple baths with distinct temperatures
Chenlin Ma, Fulu Zheng, Kewei Sun +2
We perform benchmark simulations using the time-dependent variational approach with the multiple Davydov Ansatz (mDA) to study realtime nonequilibrium dynamics in a single qubit mo…
Dynamics of dissipative Landau-Zener transitions in an anisotropic three-level system
Lixing Zhang, Lu Wang, Maxim F. Gelin +1
We investigate the dynamics of Landau-Zener transitions in an anisotropic, dissipative three-level model (3-LZM) using the numerically accurate multiple Davydov D2 Ansatz in the fr…
Schrödinger-cat states in Landau-Zener-Stückelberg-Majorana interferometry: a multiple Davydov Ansatz approach
Lu Wang, Fulu Zheng, Jiaming Wang +2
Employing the time-dependent variational principle combined with the multiple Davydov Ansatz, we investigate Landau-Zener (LZ) transitions in a qubit coupled to a ph…
Engineering Photon Delocalization in a Rabi Dimer with a Dissipative Bath
Fulu Zheng, Yuyu Zhang, Lu Wang +2
A Rabi dimer is used to model a recently reported circuit quantum electrodynamics system composed of two coupled transmission-line resonators with each coupled to one qubit. In thi…
Polaron dynamics with off-diagonal coupling: beyond the Ehrenfest approximation
Zhongkai Huang, Lu Wang, Changqin Wu +3
Treated traditionally by the Ehrenfest approximation, dynamics of a one-dimensional molecular crystal model with off-diagonal exciton-phonon coupling is investigated in this work u…
Finite-temperature time-dependent variation with multiple Davydov states
Lu Wang, Yuta Fujihashi, Lipeng Chen +1
The Dirac-Frenkel time-dependent variational approach with Davydov Ansätze is a sophisticated, yet efficient technique to obtain an acuurate solution to many-body Schrödinger equat…
Variational dynamics of the sub-Ohmic spin-boson model on the basis of multiple Davydov states
Lu Wang, Lipeng Chen, Nengji Zhou +1
Dynamics of the sub-Ohmic spin-boson model is investigated by employing a multitude of the Davydov D trial states, also known as the multi-D Ansatz. Accuracy in dynamics si…
