Nonperturbative stochastic dynamics driven by strongly correlated colored noises



报告人: 教授(吉林大学原子与分子物理研究所)


In this work, we employ a stochastic Schrödinger equation, quantum-state-diffusion (QSD) equation, that has been widely discussed in research fields ranging from atomic, molecular and optical physics to condensed matter physics and to quantum information science as a generic stochastic approach to the free and control dynamics of quantum open system. The nonequilibrium dynamics of a qubit system under the influence of two strongly correlated non-Markovian baths is studied by exactly solving an open quantum system. We show that the quantum dynamics of the qubit system is profoundly modulated by the mutual correlation between baths and the bath memory times through dissipation and fluctuation. We report a new physical effect on generating large values of the inner-correlation and entanglement of the distant two qubits arising from the strong bath correlation for a class of super-radiation states.


Dr Jun Jing got his PhD degree in 2007 at Physics Department of Shanghai Jiaotong University. Afterwards, he found a job as a lecturer at Shanghai University and got promoted as an associate professor in 2009. From 2010 to 2014, he worked as a research associate (post-Doc) at Stevens Institute of Technology, New Jersey, a visiting scholar at Department of Theoretical Physics and History of Science, The Basque Country University, Spain, and a research scientist at Physics Department, University at Buffalo, The State University of New York, in turn. Now (from June 2014) he is a full professor at the institute of Atomic and Molecular Physics, Jilin University. His works involve with the field of open quantum system dynamics, quantum control, quantum entanglement and decoherence process of AMO systems and quantum dots.
