Spring 2013
In the first part of the thesis, we study the minimally-coupled massless scalar field in de Sitter spacetime. Because of the non-linear nature of general relativity, the direct analysis of the graviton is very complicated. So, we use the scalar field as an analogue to the graviton, and shift...

Fall 2019
In this thesis we investigate how corrections originating from particle-hole interactions may be introduced into the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity using functional integral methods. The attractive Fermionic contact interaction is simultaneously decoupled in the...
