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…

Time-evolving matrix product operators for off-diagonal system-bath coupling
Chu Guo, Wei Wu, Xiansong Xu +3
The time-evolving matrix product operator (TEMPO) method has proven to be a powerful method to study the long-time dynamics of bosonic impurity problems where a small system is lin…
