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…
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…
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…
The Pegg-Barnett oscillator and its supersymmetric generalization
Jian Qi Shen
The oscillator algebra of Pegg-Barnett (P-B) oscillator with a finite-dimensional number-state space is investigated in this note. It is shown that the Pegg-Barnett oscillator poss…
Motion of a charged particle in the magnetic dipole field
Jian Qi Shen
This note discusses the motion of a charged particle in the magnetic dipole field and a modified Barut's lepton mass formula. It is shown that a charged particle in the magnetic di…
