Differential Equation Based Path Integral for System-Bath Dynamics
Geshuo Wang, Zhenning Cai
We propose the differential equation based path integral (DEBPI) method to simulate the real-time evolution of open quantum systems. In this method, a system of partial differentia…

The Wigner Function of Ground State and One-Dimensional Numerics
Hongfei Zhan, Zhenning Cai, Guanghui Hu
In this paper, the ground state Wigner function of a many-body system is explored theoretically and numerically. First, an eigenvalue problem for Wigner function is derived based o…

Inclusion-Exclusion Principle for Open Quantum Systems with Bosonic Bath
Siyao Yang, Zhenning Cai, Jianfeng Lu
We present two fast algorithms which apply inclusion-exclusion principle to sum over the bosonic diagrams in bare diagrammatic quantum Monte Carlo (dQMC) and inchworm Monte Carlo m…
