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 ...
Lessons for Conformal Field Theories from Bootstrap and Holography
(2018-02-06)
The work done in this thesis includes an exploration of both the conformal field theory techniques and holographic techniques of the Gauge/Gravity duality. From the field theory, we have analyzed the analytical aspects of ...
Flavor and Dark Matter Issues in Supersymmetric Models
(2018-04-06)
The Standard Model of particle physics attempts to unify the fundamental forces in the Universe (except gravity). Over the years it has been tested in numerous experiments. While these experimental results strengthen our ...
Direct and Indirect Search for New Physics at Colliders
The Standard Model (SM) of particle physics has been remarkably successful to describe strong, weak and electromagnetic forces of nature, as it has agreed with most of the experiments till date. However, there are still ...
Quantum dynamics of weak measurements: Understanding the Born rule and applying weak error correction
Projective measurement is used as a fundamental axiom in quantum mechanics, even though it is discontinuous and cannot predict which measured operator eigen state will be observed in which experimental run. The probabilistic ...
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 ...
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 ...
Lessons for Gravity from Entanglement
One of the recent fundamental developments in theoretical high energy physics is the AdS/CFT
correspondence [1, 2, 3, 4] which posits a relationship between Quantum Field Theories (QFT)
in a given dimension and String ...
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavy-flavour mesons as well as of direct photons,
has been used to constrain the gluon density inside the proton. In this thesis, I have assessed
various heavy flavour ...
Higgs phenomenology and Dark Matter prospects in MSSM, NMSSM and U(1) extended SM
Particle physics today is at a juncture where all particles predicted within Standard
Model (SM) have been discovered at the particle colliders while no particles from the realm
of physics beyond the Standard Model (BSM) ...
