An Exact Operator Formulation of Statistical Quasiparticle Theory for Nonlinear System-Bath Coupling
Yu Su, Yao Wang
We develop an operator formulation of statistical quasiparticle theory for open quantum systems with nonlinear system-bath coupling, extending beyond the linear coupling setting of…
Open Quantum Systems from Dynamical Constraints
Yu Su, Yao Wang
Open quantum systems are traditionally described by decomposing the total Hilbert space into a system and an external environment, linked by an explicit interaction Hamiltonian. We…
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…
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…
On the relation between momentum uncertainty and thermal wavelength
Zi-Fan Zhu, Yao Wang
For quantum particles in a Boltzmann state, we derive an inequality between momentum uncertainty and thermal de Broglie wavelength , expressed as $Δp \geq \sqrt{2π…
