Influence of 𝑳𝒊+ Substitution on Magnetic and Electrical Properties of 𝑳𝒊𝒙𝑪𝒖𝟎.𝟓𝒁𝒏𝟎.𝟓−𝟐𝒙𝑭𝒆𝟐+𝒙𝑶𝟒
(Brac University, 2018)Structural, AC magnetic and electrical properties of 𝐿𝑖𝑥𝐶𝑢0.5𝑍𝑛0.5−2𝑥𝐹𝑒2+𝑥𝑂4 (x=0.00, x=0.05, 0.10) have been investigated which were prepared by solid state reaction method. Various chemical compositions were ... 
Nonperturbative phenomena in field theory and gravity, and use of Borel summation to capture nonperturbative information
(BRAC University, 201712)This thesis addresses nonperturbative phenomena and techniques to analyze nonperturbative problems. First, we discuss the simplest nonperturbative example in quantum gravity: blackholes, and how they nonperturbatively ... 
Review of Einstein field equation solution rotational and nonrotational black holes
(BRAC University, 2017)The origin of gravitational theory of relativity includes the discussion of Sir. Isaac Newton and Einstein’s theory of relativity. A brief derivation is introduced about the spherically symmetric solution of Einstein’s ... 
Baryon acoustic oscillation and LSS formation in the nascent universe
(BRAC University, 2017)The Cosmic Microwave Background Radiation (CMBR) and cosmological redshift are together regarded as the best available evidence for the Big Bang theory. Measurements of this radiation have made the inflationary Big Bang ... 
The AdSCFT correspondence and the blackhole information theory paradox
(BRAC University, 2017)This thesis discusses the role of AdS/CFT correspondence in highenergy physics. It concentrates on studying the mathematical black holes in various backgrounds, particularly in the anti deSitter(AdS) space. In this ... 
On some general relativistic compact anisotropic charged stellar models
(BRAC University, 20150715)With the presence of electric charge and pressure anisotropy some anisotropic stellar models have been developed. An algorithm presented by Herrera et al. (Phys. Rev, D 77, 027502 (2008)) to generate static spherically ... 
Calculating the pion contribution to nucleon selfenergy using chiral effective thermal ﬁeld theory
(BRAC University, 2016)Effective ﬁeld theories have proven to be efﬁcient tools for studying physics at length scales longer than that which is typical. Chiral Perturbation Theory is one of these EFTs which physicists rely on heavily to study ... 
A review of Eikonal approximation and recent applications
(BRAC University, 201603) 
Supersymmetric gauge theory: an application of group theory in high energy physics and starobinsky model of cosmological ination
(BRAC University, 2016)This thesis discusses the general role of symmetry in highenergy physics. It concentrates on the role of fermionic symmetry generators, which generate the symmetry known as supersymmetry. An extensive discussion of ... 
Simulation of electronic properties of a quantum dot in transistor geometry at varying temperatures
(BRAC University, 201603)Electrical conduction is the ow of electron due to a force applied by an electric eld. In bulk material, conduction process obeys Ohm's law. The law states that current is proportional to applied voltage. But nanosized ... 
False vacuum decay exact computation of the classical bounce
(BRAC University, 201601)This thesis reviews the exact numerical computation of the classical bounce solution in the false vacuum decay for a quartic scalar eld potential which is o set by an external source. The decay rate in a semiclassical ...
