The Dynamics of a Modified Jaynes-Cummings Model
نویسندگان
چکیده
We introduce a dynamical system that instead of exchanging single photon as in the atomic usual Jaynes-Cummings model (JCM), it exchanges squeezed coherent photon. Accordingly, creation and annihilation operators JCM are replaced by states, respectively. This transformation generates Hamiltonian modifies includes terms usually omitted when making rotating-wave approximation and, addition, introduces atom exchange absent JCM.

Semiclassical Dynamics of the Jaynes-Cummings Model
The semiclassical approximation of coherent state path integrals is employed to study the dynamics of the Jaynes-Cummings model. Decomposing the Hilbert space into subspaces of given excitation quanta above the ground state, the semiclassical propagator is shown to describe the exact quantum dynamics of the model. We also present a semiclassical approximation that does not exploit the special p...
متن کاملDynamics of Bloch vector in thermal Jaynes-Cummings model
In this paper, we investigate the dynamics of the Bloch vector of a single two-level atom which interacts with a single quantized electromagnetic field mode according to the Jaynes-Cummings model, where the field is initially prepared in a thermal state. The time evolution of the Bloch vector S(t) seems to be in complete disorder because of the thermal distribution of the initial state of the f...
متن کاملGrassmann Variables and the Jaynes-cummings Model
1 0.1 Abstract The Jaynes-Cummings model of a two-level atom in a single mode cavity is of fundamental importance both in quantum optics and in quantum physics generally , involving the interaction of two simple quantum systems-one fermionic system (the TLA), the other bosonic (the cavity mode). Depending on the initial conditions a variety of interesting effects occur, ranging from ongoing osc...
متن کاملNonlinear Jaynes-Cummings dynamics of a trapped ion.
The Lindblad approach to open quantum systems is introduced for studying the dynamics of a single trapped ion prepared in nonclassical motional states and subjected to continuous measurement of its internal population. This results in an inhibition of the dynamics similar to the one occurring in the quantum Zeno effect. In particular, modifications to the Jaynes-Cummings collapses and revivals ...
متن کاملJaynes-cummings Model with Degenerate Atomic Levels
The Jaynes-Cummings model describing the interaction of a single linearlypolarized mode of the quantized electromagnetic field with an isolated two-level atom is generalized to the case of atomic levels degenerate in the projections of the angular momenta on the quantization axis, which is a usual case in the experiments. This generalization, like the original model, obtains the explicit soluti...
