Photon counting statistics in the presence of spectral diffusion induced by nonequilibrium environmental fluctuations
Xiangji Cai, Yonggang Peng, Yujun Zheng
We theoretically investigate the statistical properties of photon emission of a driven two-level single-molecule system undergoing spectral diffusion induced by nonequilibrium envi…
Quantum decoherence dynamics in stochastically fluctuating environments
Xiangji Cai, Yanyan Feng, Jing Ren +2
We theoretically study the decoherence of a two-level quantum system coupled to noisy environments exhibiting linear and quadratic fluctuations within the framework of a stochastic…
Quantum coherent dynamics in single molecule systems: generalized stochastic Liouville equation
Xiangji Cai, Yujun Zheng
We propose the generalized stochastic Liouville equation to investigate the coherent dynamics in single molecule systems coupled to environments which exhibit both nonstationary an…
Geometric phases between biorthogonal states
Xiao-Dong Cui, Yujun Zheng
We investigate the evolution of a state which is dominated by a finite-dimensional non-Hermitian time-dependent Hamiltonian operator with a nondegenerate spectrum by using a biorth…
Quantum interference in a four-level system of a atom: Effects of spontaneously generated coherence
Dongsheng Wang, Yujun Zheng
In this work, the effects of quantum interference and spontaneously generated coherence (SGC) are theoretically analyzed in a four level system of a atom. For th…
