Measurement of the mechanical reservoir spectral density in optomechanical system
Wen-Zhao Zhang, Xian-Ting Liang, Jiong Cheng +1
To investigate the dynamical behavior of a quantum system embedded in a memory environment, it is crucial to obtain the knowledge of the reservoir spectral density. However, such k…
The Lindblad and Redfield forms without secular approximation derived from Born-Markov master equation and their applications
Chang-Yao Liao, Xian-Ting Liang
In this paper we derive the Lindblad and Redfield forms with and without secular approximation from the Born-Markov master equation for open quantum systems. The spectral correlati…
Time evolution of spin-boson system for different effective spectral density functions
Xian-Ting Liang
In this paper we firstly obtain two kinds of effective spectral density functions by setting the cut-off frequencies of baths be infinite and finite. Secondly, we investigate the r…
Decoherence of coherent electronic excited state in the reaction center of the photosynthetic purple bacterium Rhodobacter sphaeroides
Xian-Ting Liang, Wei-Min Zhang, Yi-Zhong Zhuo
In this paper, we present a theoretical description to the quantum coherence and decoherence phenomena of energy transfer in photosynthesis observed in a recent experiment [see Sci…
Study of the decoherence of a double quantum dot charge qubit via the Redfield equation
Zeng-Zhao Li, Xiao-Yin Pan, Xian-Ting Liang
By using the Redfield form of the master equation, we investigate the decoherence times of a double quantum dot charge qubit (DQDCQ) in three different cases, namely when it is cou…
Decoherence and purity of a driven solid-state qubit in Ohmic bath
Zhi-Qiang Li, Xian-Ting Liang
In this paper we study the decoherence and purity of a driven solid-state qubit in the Ohmic bath by using the method based on the master equation. At first, instead of solving the…
