Accelerated Inchworm Method with Tensor-Train Bath Influence Functional

Geshuo Wang, Yixiao Sun, Siyao Yang +1

We propose an efficient tensor-train-based algorithm for simulating open quantum systems with the inchworm method, where the reduced dynamics of the open quantum system is expresse…

Solving Caldeira-Leggett Model by Inchworm Method with Frozen Gaussian Approximation

Geshuo Wang, Siyao Yang, Zhenning Cai

We propose an algorithm that combines the inchworm method and the frozen Gaussian approximation to simulate the Caldeira-Leggett model in which a quantum particle is coupled with t…
