The term'nonclassical states' refers to the quantum states that cannot be produced in the
usual sources of light, such as lasers or lamps, rather than those requiring more …

We discuss the creation of entanglement between two two-level atoms in the dissipative
process of spontaneous emission. It is shown that spontaneous emission can lead to a …

Two-dimensional (2D) systems with time-dependent controls admit a quadratic Hamiltonian
modeling near potential minima. Independent, dynamical normal modes facilitate inverse …

We give a simplified form of Simon's separability criterion for two-mode Gaussian states,
showing that for systems whose unitary evolution is governed by arbitrary time-dependent …

The problem of a charged particle in the presence of a variable magnetic field is considered.
Using the linear and the quadratic invariants as a tool, the wave functions in Fock state as …

Several aspects of the stimulated Raman scattering process are studied using the model of
a two-dimensional oscillator. The photons of the Stokes mode are taken as one mode of the …

We study the dynamics of the coefficient of quantum separability between resonantly
coupled modes of the massless scalar field in a one-dimensional ideal cavity, whose …

We introduce several coefficients characterizing the degree of intermode correlations and
inseparability for multimode continuous variable quantum systems. All these coefficients are …

We introduce the measure of entanglement of continuous variable quantum systems,
expressed in terms of the cross-covariances of the quadrature components or the …

A system consisting of two identical single-mode cavities coupled to a common environment
is investigated within the framework of algebraic dynamics. Based on the left and right …
