Extended dissipaton theory for higher-order bath couplings and application to non-Condon spectroscopy with anharmonicity
Zi-Fan Zhu, Yu Su, Yao Wang +2
In this work, we develop an extended dissipaton theory that generalizes the environmental couplings beyond the conventional linear and quadratic forms, enabling the treatment of ar…
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…
Correlated vibration-solvent and Duschinsky effects on electron transfer dynamics and optical spectroscopy
Zi-Fan Zhu, Yu Su, Yao Wang +2
Understanding the effects of vibrations in electron transfer (ET) dynamics and optical spectroscopies is essential to precisely interpret the role of decoherence, especially for sy…
Stochastic Equation of Motion Approach to Fermionic Dissipative Dynamics. II. Numerical Implementation
Arif Ullah, Lu Han, Yun-An Yan +3
This paper provides a detailed account of the numerical implementation of the stochastic equation of motion (SEOM) method for the dissipative dynamics of fermionic open quantum sys…
Stochastic Representation of Non-Markovian Fermionic Quantum Dissipation
Lu Han, Vladimir Chernyak, Yun-An Yan +2
Quantum Brownian motion plays a fundamental role in many areas of modern physics. In the path-integral formulation, the environmental quantum fluctuations driving the system dynami…
