Berry's phase at quantum vacuum level
Jian Qi Shen
The quantum vacuum contribution to Berry's geometric phase of photon fields inside a noncoplanarly curved (coiled) fiber is considered by means of the second-quantization formulati…
The supersymmetric Pegg-Barnett oscillator
Jian Qi Shen
The su Lie algebraic structure of the Pegg-Barnett oscillator that possesses a finite-dimensional number-state space is demonstrated. The supersymmetric generalization of Pegg…
On the quantum vacuum contribution to the momentum of dielectric media
Jian Qi Shen
More recently, Feigel has considered the quantum vacuum contribution to the momentum of electromagnetic media. However, in Feigel's treatment he did not take into account the relat…
Explicit formula for the external driving field used to eliminate the decoherence of a two-state system coupled to a noise field
Jian-Qi Shen, Zhi-Chao Ruan, Sailing He
The elimination of decoherence of a multiphoton two-state quantum system by using an appropriate external driving field is considered. The multiphoton process caused by the noise f…
Influence of the signal light on the transient optical properties of a four-level EIT medium
Jian-Qi Shen, Zhi-Chao Ruan, Sailing He
General formulae for the transient evolution of the susceptibility (absorption) induced by the quantum interference effect in a four-level N-type EIT medium is presented. The influ…
Automatical generation of nonadiabatic conditional geometric phase shift via a noncoplanar fiber system
Jian Qi Shen
A new scheme of realizing the nonadiabatic conditional geometric phase shift via a noncoplanar (and coiled) fiber system is presented in this Letter. It is shown that the effective…
