Calculating the pion contribution to nucleon self-energy 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, 2016-03)
Simulation of electronic properties of a quantum dot in transistor geometry at varying temperatures
(BRAC University, 2016-03)
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 ...
False vacuum decay exact computation of the classical bounce
(BRAC University, 2016-01)
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 ...
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 high-energy physics. It concentrates
on the role of fermionic symmetry generators, which generate the symmetry known as
supersymmetry. An extensive discussion of ...
