Local thermal probe in a one-dimensional chain: An efficient dissipaton-based approach
Hao-Yang Qi, Zi-Fan Zhu, Yao Wang +2
We study a system consisting of an infinite one-dimensional molecular chain and a locally coupled probe. Starting from the Hamiltonian of the chain-probe composite and the correspo…
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…
Fermionic influence superoperator for transport through Majorana zero modes
Jia-Lin Pan, Zi-Fan Zhu, Shixuan Chen +2
In recent years, the study of Majorana signatures in quantum transport has become a central focus in condensed matter physics. Here, we present a rigorous and systematic derivation…
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…
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…
