This thesis addresses non-perturbative phenomena and techniques to analyze nonperturbative
problems. First, we discuss the simplest non-perturbative example in
quantum gravity: blackholes, and how they non-perturbatively ...
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 ...
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 ...
This thesis discusses the role of AdS/CFT correspondence in high-energy physics. It
concentrates on studying the mathematical black holes in various backgrounds, particularly in
the anti deSitter(AdS) space. In this ...
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 ...
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 ...
This thesis discusses the general role of symmetry in high-energy physics. It concentrates
on the role of fermionic symmetry generators, which generate the symmetry known as
supersymmetry. An extensive discussion of ...
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 nano-sized ...
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 ...
