Entanglement and non-Markovianity of a multi-level atom decaying in a cavity
《Chinese Physics B》2016年第1期440-445,共6页范子龙 任玉坤 曾浩生 
supported by the National Natural Science Foundation of China(Grant Nos.11275064 and 11075050);the Specialized Research Fund for the Doctoral Program of Higher Education,China(Grant No.20124306110003);the Construct Program of the National Key Discipline,China
We present a paradigmatic method for exactly studying non-Markovian dynamics of a multi-level V-type atom interacting with a zero-temperature bosonic bath. Special attention is paid to the entanglement evolution and t...

Phase effect on dynamics of quantum discord modulated by interaction between qubits被引量：1
《Chinese Physics B》2015年第9期101-105,共5页王国友 郭有能 曾浩生 
Project supported by the National Natural Science Foundation of China(Grant Nos.11275064 and 11075050);the Specialized Research Fund for the Doctoral Program of Higher Education,China(Grant No.20124306110003);the Scientific Research Foundation of the Education Department of Hunan Province,China(Grant No.13C039);the Construct Program of the National Key Discipline,China
We study the effects of the interaction strength and the initial phase on the dynamics of quantum discord in a twoqubit system under both spontaneous emission and dephasing noisy channels. It is shown that the time ev...

Rotation of Bloch sphere induced by Lamb shift in open two-level systems
《Chinese Physics B》2015年第5期198-203,共6页王国友 唐宁 刘颖 曾浩生

From a quite general form of the Lindblad-like master equation of open two-level systems （qubits）, we study the effect of Lamb shift on the non-Markovian dynamics. We find that the Lamb shift can induce a non-unifor...

Entanglement and non-Markovianity of a spin-S system in a dephasing environment
《Chinese Physics B》2014年第6期30-36,共7页范子龙 田晶 曾浩生 
supported by the National Natural Science Foundation of China(Grant Nos.11275064 and 11075050);the Specialized Research Fund for the Doctoral Program of Higher Education of China(Grant No.20124306110003);the Program for Changjiang Scholars and Innovative Research Team in Universities of China(Grant No.IRT0964);the Construct Program of the National Key Discipline
We study the entanglement （measured by negativity） evolution and the non-Markovianity for the dynamical process of a spin-S system embedded in dephasing environments. The exact analytical solution is presented, whic...

Project supported by the National Natural Science Foundation of China (Grant Nos. 11275064 and 11075050);the National Basic Research Program of China(Grant No. 2007CB925204);the Construct Program of the National Key Discipline,China
In the limit of weak coupling between a system and its reservoir,we derive the time-convolutionless（TCL） nonMarkovian master equation for a two-level system interacting with a zero-temperature structured environment...
