Projection-Based Memory Kernel Coupling Theory for Quantum Dynamics: A Stable Framework for Non-Markovian Simulations
Wei Liu, Rui-Hao Bi, Yu Su +4
We present a projection-based, stability-preserving methodology for computing time correlation functions in open quantum systems governed by generalized quantum master equations wi…
The Phase-Coupled Caldeira-Leggett Model: Non-Markovian Open Quantum Dynamics beyond Linear Dissipation
Ao-Xiang Chang, Yu Su, Zi-Fan Zhu +3
We introduce the \textit{Phase-Coupled Caldeira-Leggett} (PCL) model of quantum dissipation and develop an exact framework for its dynamics. Unlike the conventional Caldeira-Legget…
Optimal control on open quantum systems and application to non-Condon photo-induced electron transfer
Zi-Fan Zhu, Yu Su, Yao Wang +1
In this work, we develop an optimal control theory on open quantum system and its environment, and exemplify the method with the application to the non-Condon photo-induced electro…
Nonperturbative Open Quantum Dynamics Bypass Influence Functional
Yu Su, Yao Wang, Wenjie Dou
An ordered moment approach to exact open quantum dynamics is presented, which bypasses the Feynman-Vernon influence functional formalism. The hierarchical equations of motion are c…
Dissipatons as generalized Brownian particles for open quantum systems: Dissipaton-embedded quantum master equation
Xiang Li, Yu Su, Zi-Hao Chen +4
Dissipaton theory had been proposed as an exact and nonperturbative approach to deal with open quantum system dynamics, where the influence of Gaussian environment is characterized…
Stability of Quantum Systems beyond Canonical Typicality
Yu Su, Zi-Fan Zhu, Yao Wang +2
Involvement of the environment is indispensable for establishing the statistical distribution of system. We analyze the statistical distribution of a quantum system coupled strongl…
