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 ...
In this thesis, we present the effect of attractive polymer-wall interaction on the translocation of a polymer chain moving through nanochannel in the absence of external force
using dynamical Monte Carlo simulations. An ...
In this thesis, before we were going to study these effects on thermoluminesce peaks,
the phenomenon of both luminescence and thermoluminesce as well as the types
of luminescence were explained. we study theatrical and ...
We have studied the optical properties of nanospherical metal inclusions in dielectric
host matrix. Both analytical and numerical methods are employed for analyzing this
nano composite system. The real and imaginary part ...
Currently, the science of astronomy for the study of origins and evolutions is advancing both theoretically and observationally. However, there are a number of works
for further developments. For example, the data extracted ...
The increasing interest in optical properties of the composite media is dictated by the fact that small particles, which are randomly embedded in a linear dielectric host matrix, can be manufactured with the help of modern ...
When crystals are constructed on a smaller scale (nanometeric scale), the energy gap between the highest occupied molecular orbital and the lowest unoccupied molecular orbital increased. In this thesis, quantum confinement, ...
