Tree-based Implementation of the Small Matrix Path Integral for System-Bath Dynamics
Geshuo Wang, Zhenning Cai
The small matrix path integral (SMatPI) method is an efficient numerical approach to simulate the evolution of a quantum system coupled to a harmonic bath. The method relies on a s…
The Bold-Thin-Bold Diagrammatic Monte Carlo Method for Open Quantum Systems
Zhenning Cai, Geshuo Wang, Siyao Yang
We present two diagrammatic Monte Carlo methods for quantum systems coupled with harmonic baths, whose dynamics are described by integro-differential equations. The first approach…
Asymptotic analysis of diabatic surface hopping algorithm in the adiabatic and non-adiabatic limits
Zhenning Cai, Di Fang, Jianfeng Lu
Surface hopping algorithms, as an important class of quantum dynamics simulation algorithms for non-adiabatic dynamics, are typically performed in the adiabatic representation, whi…
Fast Algorithms of Bath Calculations in Simulations of Quantum System-Bath Dynamics
Zhenning Cai, Jianfeng Lu, Siyao Yang
We present fast algorithms for the summation of Dyson series and the inchworm Monte Carlo method for quantum systems that are coupled with harmonic baths. The algorithms are based…
