Long Time Behaviour of the Field in a Lossless Micromaser with Intensity-dependent Coupling Constant

Igor Jex, Henryk Paul

Published Dec 1, 1993• 3 citations
Publisher

Abstract

Using the asymptotic form of the density matrix the role of the non-diagonal elements of the density matrix is estimated in the lossless micromaser model based on the Jaynes-Cummings model with intensity dependent coupling constant. It is shown that a certain type of a (almost pure) multiphoton state can be generated in this system.

Long-term Behaviour of the Field in a Lossless Microscopic Maser

Henryk Paul

An asymptotic form of the density matrix for the field inside the cavity of a microscopic maser is derived. It is shown that it contains essentially the same information as that which has been inferred from numerical experiments in which the results of repeated measurements on the atoms as they leave the cavity have been taken into account. In particular, both approaches predict that the field, which is assumed to be initially of a thermal nature, evolves towards certain ‘trapping levels’. The analytic approach presented here is more general since it includes the evaluation of non-diagonal matrix elements.

Generation of nonlinear coherent states in a coherently pumped micromaser under intensity-dependent Jaynes-Cummings model

M. H. Naderi, M. Soltanolkotabi, R. Roknizadeh

In this paper the possibility of generating nonlinear coherent states of the radiation field in a micromaser is explored. It is shown that these states can be provided in a lossless micromaser cavity under the weak Jaynes-Cummings interaction with intensity-dependent coupling of large number of individually injected two-level atoms in a coherent superposition of the upper and lower states. In particular, we show that the so-called nonlinear squeezed vacuum and nonlinear squeezed first excited states, as well as the even and odd nonlinear coherent states can be generated in the presence of two-photon transitions.

Generalized Jaynes-Cummings Model with Intensity-Dependent and Non-resonant Coupling

A N F Aleixo, A. B. Balantekin, Ribeiro, M. A. Candido

We study the intensity-dependent and nonresonant Jaynes-Cummings Hamiltonian when the field is described by an arbitrary shape-invariant system. We determine the eigenstates, eigenvalues, time evolution matrix and the population inversion matrix factor.

Atom-field entanglement for Jaynes–Cummings model with an intensity-depend coupling

Eugene K. Bashkirov, Eugenya V Grishina, Elena Yu Sochkova

We investigate the evolution of a quantum system described by the two-atom Jaynes–Cummings model with an intensity-dependent couplings by displaying the linear atomic entropy and the asymptotic behavior of state vector. The possibility of the system being initially in a pure disentangled state to revive into this state during the evolution process is shown. Conditions and times of disentanglement are derived.

The dynamical properties in the nonlinear Jaynes-Cummings model

YX Huang, Y Wang, Zhan Zhan

The properties of state evolution of the atom, field, and atom-field systems in the intensity-dependent coupling Jaynes-Cummings Model with an additional Kerr medium are investigated by using the distance between density operators. The effects of nonlinearity interaction of Kerr medium and the average photon number of initial coherent field on the dynamical behaviour of the quantum system are discussed in comparison with the one-photon Jaynes-Cummings model with an additional Kerr medium.
