Leg-Tied Tensor Network States: Entanglement Beyond Virtual Bonds
Shuoyi Hu, Bing Gu
We introduce a class of tensor-network states in which physical legs are shared among local tensors, termed leg-tied tensor ansätze (LETTA). Physical leg ties encode long-range cor…
Nonadiabatic Renormalization Group for Strongly Coupled Multiscale Quantum Systems
Bing Gu
Complex quantum systems are often multiscale in nature with strong interactions between different scales. We present a novel idea: iteratively suppressing, rather than tracing out,…
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…
