Density matrix renormalization group in the discrete variable representation basis
Bing Gu
We present a numerical implementation of the density matrix renormalization group (DMRG) using the discrete variable representation (DVR) basis set. One main advantage of using the…

Diagrammatic representation and nonperturbative approximation of exact time-convolutionless master equation
Bing Gu
The time-convolutionless master equation provides a general framework to model non-Markovian dynamics of an open quantum system with a time-local generator. A diagrammatic represen…
