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…

Chaotic-Integrable Transition for Disordered Orbital Hatsugai-Kohmoto Model
Ying-Lin Li, Chen-Te Ma, Po-Yao Chang
We have drawn connections between the Sachdev-Ye-Kitaev model and the multi-orbit Hatsugai-Kohmoto model, emphasizing their similarities and differences regarding chaotic behaviors…
