Quantum phase properties of photon added and subtracted displaced Fock states (and their
limiting cases) are investigated from a number of perspectives, and it is shown that the …

Conventional coherent states (CSs) are defined in various ways. For example, CS is defined
as an infinite Poissonian expansion in Fock states, as displaced vacuum state, or as an …

Quantum dynamics of a four-channel nonlinear directional coupler, based on Kerr effect,
was modeled numerically by a set of stochastic differential equations derived using …

Various lower-and higher-order nonclassical properties have been studied for two physical
systems-(i) an optomechanical system composed of a Fabry-Perot cavity with one …

From the perspective of quantum optics, various lower-and higher-order nonclassical
features of correlations have been studied for two physical systems-(i) an optomechanical …

The coherent light interacting with a direct band-gap semiconductor is modelled as two
coupled harmonic oscillators with Kerr-type nonlinearity in one of the oscillators. By …

The main focus of this thesis is to study the nonclassical and phase properties of a family of
engineered quantum states, most of which show various nonclassical features. The beauty …

The quasi-potential approach is very famous in modern relativistic particles physics. This
approach is based on the so-called covariant single-time formulation of quantum field theory …
