We study the algebraic structure of the one-dimensional Dirac oscillator by extending the concept of spin symmetry to a noncommutative case.An SO(4)algebra is found connecting the eigenstates of the Dirac oscillator,i...

The effects of counter-rotating terms(CRTs)on Rabi splitting and the dynamic evolution of atomic population in the Jaynes–Cummings model are studied with a coherent-state approach.When the coupling strength increases...

We consider a theoretical scheme for entanglement transfer between a two-mode squeezed vacuum field and two initially separable atoms through intensity-dependent couplings. We find that the entanglement transfer betwe...

We present the first results for the analytic solution of the dissipative Jaynes-Cummings model and its application to the collapse and revival of atomic inversion. We find that the atomic inversion oscillates more an...

Unified and standardized solving formulas for eigenvalues,eigenvectors,evolution operators,time-varying atomic inversion and photon numbers are given to single-mode Jaynes-Cummings models with any forms of intensity-d...
In this paper,a semiclassical approach to trapping problem of atoms in Jaynes-Cummings model is presented.The detuning is expressed by considering detuning as superposition of plenty of harmonic waves.Appearance of tr...

Introducing a dressed-state description,we show that a trapped ion in a standing wave field can be described by a nonlinear Jaynes-Cummings model different from the counterpart of Vogel and Matos Filho[Phys.Rev.A 52(1...

We have studied the influence of thermal photons on the symmetry between the field and atomic squeezing(SFAS)exposed in the resonant vacuum-field Jaynes-Cummings model with an initially coherent atom.We have shown tha...
A symmetric structure of the field and atomic squeezing(SSFAS)have been exposed in the resonant Ja.ynes-Cummings model when it is restricted to the following initial condition:the atom in its ground state and the fiel...
