Analytical Mellin-Barnes techniques with applications to two-loop SU(3) chiral perturbation theory and QED at higher loops
The present era is one of precision in particle physics. To account for the lacunae in the otherwise successful Standard Model, observables are calculated to high precision in various theoretical models, which are then ... -
Applications of Holography
This thesis consists of four parts. In the first part of the thesis, we investigate the phase structure of Einstein-Maxwell-Scalar system with a negative cosmological constant. For the conformally coupled scalar, an ... -
Aspects of conformal field theories at finite temperature
In this thesis we have studied broadly two aspects of thermal field theory. We began by examining how the macroscopic system (described by relativistic hydrodynamics) behalves in presence of microscopic anomalies. We ... -
Aspects of time dependence in quantum quenches
In this thesis we study the time dependence of correlators such as Green function, entanglement (Renyi) entropy and mutual information following quantum quench in Conformal Field Theories (CFTs) and their holographic duals ... -
Efficient Quantum Algorithms for Linear Algebra Problems
Many simulation problems can be expressed as time evolution under specific interactions, from some simple initial state to a final state whose properties are to be investigated. In this context, the Hamiltonian evolution ... -
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 ... -
Living on the Edge A Study of Boundary Modes In Two-dimensional Topological Systems
In the last few decades an enormous amount of research has been carried out on some novel phases of matter called topological phases which are beyond the paradigm of Landau’s theory of symmetry breaking. One of the ... -
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 ...
