In this thesis, we have investigated the squeezing and statistical properties of light
produced by coherently driven degenerate three-level laser with parametric amplifier for the cavity mode coupled to a vacuum reservoir ...
The dynamics of a coherently driven two level laser with vacuum reservoir is analyzed. The combination of interaction Hamiltonian and Langevin equation is presented to study the quantum properties of light. By using these ...
In this thesis we considered the flat CDM cosmological model to constrain the density parameters,
the Hubble constant and the age of the universe. We did also estimate the mass of the universe
setting some relevant ...
We analyze density operator, Q function, photon statistics, quadrature
squeezing, and Cv entanglement that holds true for a pair of superposed
two-mode photon system. We also present a slightly modified definition ...
Weanalyze the CV bipartite entanglement of the light generated by a coherently pumped non degenerate three-level laser with a two-mode subharmonic generator coupled to a two-mode vacuum reservoir via a single-port mirror, ...
In this article, we have analyzed the squeezing and statistical properties of the light generated by
the superposition of second harmonic light and degenerate three level squeezed laser beams. We have
found that the mean ...
The electronic and structural properties of Iron (Fe) were investigated using density functional theory (QUANTUM ESPRESSO). Iron is the main ingredient used to
make steel and the crystalline structure is body center cubic ...
The discovery of gravitational lensing made the deflection of light as an important tool for
astronomy and cosmology. Since Einstein introduced general theory of relativity for the expanding
universe, the cosmological ...
In this thesis, we study the squeezing and statistical properties of light
produced by degenerate squeezed three level laser and one mode
subharmonic generator. We first obtain, the master equation, with the aid of
the ...
In this thesis, we have analyzed the photon statistic and quadrature fluctuations of the degenerate three level laser coupled to thermal reservoir. We have found that the mean photon number of the system under consideration ...
The optical properties of a semiconductor can be defined as any property that involves the interaction between electromagnetic radiation or light and the semiconductor, including absorption, diffraction, polarization, ...
The main objective of this study was to examine the Light bends when it
passes around an edge or through a silt. This bending of light called diffraction.
You can easily demonstrate diffraction using a candle or a small ...
More recent literature reviews point out that most galaxies, especially early type galaxies
with Active Galactic Nuclei (AGNs), contain Massive Black Holes (MBHs) considered to be
comparable to the masses of high redshift ...

The interaction of the solar wind magnetic field with the Earth’s magnetosphere has a great effect on the near-Earth space environment. This space weather interaction further affects human life activities and life on earth. ...
In this research, we have studied the squeezing and statistical properties of the cavity
light beams produced by a dynamics of non-degenerate three-level laser in a closed
cavity and coupled with a two-mode vacuum reservoir ...
The Schwarzschild solution is unique and its metric can be interpreted as the exterior
gravitational field of a spherically symmetric mass. Most of the experimental tests
of general relativity were based on the Schwarzschild ...

Today the science astronomy for the study of origins and evolutions has at an advancing level both theoretically and observationally. However, there are a number of works for further developments. For example, the data ...
Active Galactic Nuclei (AGNs) are amongst important astrophysical systems used in astrophysical studies that require diverse areas of physics entertaining from quantum field to
gravitation. Its interaction with its ...
