Positivity Preserving non-Markovian Master Equation for Open Quantum System Dynamics: Stochastic Schrödinger Equation Approach
Wufu Shi, Yusui Chen, Quanzhen Ding +2
Positivity preservation is naturally guaranteed in exact non-Markovian master equations for open quantum system dynamics. However, in many approximated non-Markovian master equatio…
Exact coherence dynamics mediated by a single cavity mode in the presence of leakage
Yusui Chen, Quanzhen Ding, Wufu Shi +2
We present a quantum-state-diffusion equation to characterize the dynamics of a generic atomic system coupled to a leaky cavity mode. As quantum resources, the population, the cohe…
Open system approach to non-equilibrium dynamical theory of quantum dot systems
Wufu Shi, Yusui Chen, Lihui Sun +2
We theoretically investigate the non-equilibrium quantum dynamical theory of a quantum dot system coupled to fermionic reservoirs using the recently developed stochastic fermionic…
Measurement Back Action on Qubit Systems by a Cavity Probe
Yusui Chen, Wufu Shi, Debing Zeng +1
We study the back action on a coupled multiple-qubit system induced by a quantum cavity probe in a non-demolition quantum measurement scheme. The exact quantum state stochastic Sch…
Non-Markovian Dynamics of Quantum Open Systems Embedded in a Hybrid Environment
Xinyu Zhao, Wufu Shi, J. Q. You +1
Quantum systems of interest are typically coupled to several quantum channels (more generally environments). In this paper, we develop an exact stochastic Schrödinger equation for…
Fermionic Stochastic Schrödinger Equation and Master Equation: An Open System Model
Xinyu Zhao, Wufu Shi, Lian-Ao Wu +1
This paper considers the extension of the non-Markovian stochastic approach for quantum open systems strongly coupled to a fermionic bath, to the models in which the system operato…
Non-Markovian Fermionic Stochastic Schrödinger Equation for Open System Dynamics
Wufu Shi, Xinyu Zhao, Ting Yu
In this paper we present an exact Grassmann stochastic Schrödinger equation for the dynamics of an open fermionic quantum system coupled to a reservoir consisting of a finite or in…
Implementation of a single femtosecond optical frequency comb for rovibrational cooling
W. Shi, S. Malinovskaya
We show that a single femtosecond optical frequency comb may be used to induce two-photon transitions between molecular vibrational levels to form ultracold molecules, e.g., KRb. T…
