Grassmann time-evolving matrix product operators for fermionic impurities coupled to a superconducting bath
Chu Guo, Wei Wu, Xiansong Xu +4
The Grassmann time-evolving matrix product operator (GTEMPO) method, which represents the Feynman-Vernon influence functional as a temporal matrix product state, has been shown to…

Stark-induced tunable phase transition in the two-photon Dicke-Stark model
Cui-Lu Zhai, Wei Wu, Chun-Wang Wu +1
We theoretically investigate the superradiant phase transition (SPT) in the two-photon Dicke-Stark model, which incorporates both Rabi and Stark coupling. By introducing a Stark co…
