Coherent States and Squeezed States in Interacting Fock Space

In this paper we study coherent states and squeezed states in one mode interacting Fock space.

Eigenvectors of Backwardshift on a Deformed Hilbert Space

We study reproducing kernel and Coherent vectorsin a deformed Hilbert space.

Quasiprobability Distribution and Phase Distribution in Interacting Fock Space

In this paper we study quasiprobability distribution and phase distribution for coherent states, squeezed states, and Kerr states in one-mode interacting Fock space.

Orthogonal Even Nonlinear Coherent States

We introduce orthogonal even nonlinear coherent states and study theirstatistical properties.

BERRY PHASE OF ATOM-FIELD SYSTEM IN INTERACTING FOCK SPACE

Starting with the interaction of interacting field and a two level atom we observe that the atom-interacting field system acquires a space parameter dependent Berry phase after the phase parameter slowly changes and ultimately returns to its initial form.

Squeezed Vector and Its Phase Distribution in a Deformed Hilbert Space

In this paper we study squeezed vectors, squeezed Kerr vectors, and their phase distributions in a deformed Hilbert space.

Nonlinear Phase Changes in a Deformed Hilbert Space

In this paper we study nonlinear phase changes of some states with respect to a phase distribution on a deformed Hilbert space.

Probability Operator Measure and Phase Measurement in a Deformed Hilbert Space

We discuss the probability operator measure and phase measurement in a deformedHilbert space.

An experimental scheme to generate nonclassical states in interacting Fock space

An experimentally realizable scheme is considered for manipulating quantum states using a general superposition (SUP) of products of interacting annihilation and creation operators. Application of such an operation on states with classical features introduces strong nonclassicality. This provides the possibility of engineering quantum states with nonclassical features.

NONCLASSICAL STATES IN INTERACTING FOCK SPACE

The time evolution of one mode interacting field which interacts with a vee-configuration three-level atom has been discussed. Generated nonclassical state has been utilized to study population inversion of atom and the total noise of the system. Also nonclassicality of the system is shown with the help of Mandels parameter.
