Studies of Feynman and Related Integrals and their Hypergeometric Connection using the Method of Brackets, Algebraic Relations and Singularity Analysis
Feynman integrals are special kind of integrals that arise in perturbative quantum field theory and are often very difficult to evaluate in terms of known functions of mathematical physics. At times some of the methods ... -
Studies of Topological Phases of Matter : Presence of Boundary Modes and their Role in Electrical Transport
(2018-05-21)Topological phases of matter represent a new phase which cannot be understood in terms of Landau’s theory of symmetry breaking and are characterized by non-local topological properties emerging from purely local (microscopic) ... -
A Study of the Low-Energy Spectrum and Phase Structure of a Yang-Mills Matrix Model
Yang-Mills theory is a non-Abelian gauge theory based on the gauge group SU(N), and lies at the heart of the QCD, the theory underlying strong interactions. Due to the fundamental property of asymptotic freedom, a study ... -
Topics In Noncommutative Gauge Theories And Deformed Relativistic Theories
(2015-08-12)There is a growing consensus among physicists that the classical notion of spacetime has to be drastically revised in order to nd a consistent formulation of quantum mechanics and gravity. One such nontrivial attempt ... -
Topics in the Exploration of New Physics at the International Linear Collider with the inclusion of Beam Polarization
(2018-04-03)The Standard Model of particle physics which attempts to describe all matter and all forces in the universe (except gravity),has been in agreement with most of the experiments till date. However theoretically and ... -
Topological Phases, Majorana Modes, Dynamics and Transport in One-Dimensional Systems
This thesis presents work done on topological phases, Majorana modes, dynamics and transport in various system like the Kitaev models in one and two dimensions and systems with junctions of a p-wave superconductor and ... -
Transport and criticality in topological systems and spin models
This thesis presents work done on transport in topological insulators and graphene-based systems, and quantum criticality in one- and two-dimensional spin models. In particular we study the following: transport on surfaces ... -
Transport In Quasi-One-Dimensional Quantum Systems
(2011-04-01)This thesis reports our work on transport related problems in mesoscopic physics using analytical as well as numerical techniques. Some of the problems we studied are: effect of interactions and static impurities on the ... -
Understanding Conformal Field Theory in Mellin Space
In the last decade, there has been tremendous progress in understanding conformal eld theories in more than two space-time dimensions. The numerical bootstrap framework has been pushed to a very advanced level of ...
