Aspects of Higher Spin Theories Conformal Field Theories and Holography
(2018-05-30)
This dissertation consist of three parts. The first part of the thesis is devoted to the study of gravity and higher spin gauge theories in 2+1 dimensions. We construct cosmological so-lutions of higher spin gravity in 2+1 ...
Probing Higgs Boson Interactions At Future Colliders
(2010-11-11)
We present in this thesis a detailed analysis of Higgs boson interactions at future colliders. In particular we examine, in a model independent way, the sensitivity of an
Linear Collider in probing the interaction of ...
Probing the Beyond Standard Model Physics in Top Quark and Dark Matter Sectors
(2018-05-22)
The Standard Model (SM) of particle physics provides the theoretical framework to describe the fundamental interactions among elementary constituents of matter. SM is supported by experiments to a high degree of accuracy, ...
An Efficient Quantum Algorithm and Circuit to Generate Eigenstates Of SU(2) and SU(3) Representations
(2018-04-18)
Many quantum computation algorithms, and processes like measurement based quantum computing, require the initial state of the quantum computer to be an eigenstate of a specific unitary operator. Here we study how quantum ...
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) ...
Issues in Phenomenology of Heavy Quarks And Leptons
(2017-09-26)
The Standard Model (SM) of the particle physics, based on the gauge group SU(3) ×SU(2)L × U(1)Y , has been a successful theory which provides consistent description of all phenomena ranging from the nuclear beta decay to ...
Conformal Bootstrap : Old and New
(2018-05-25)
Conformal Field Theories (CFT) are Quantum Field Theories characterized by enhanced (conformal) symmetries. They are interesting to Theoretical Physicists because they occur at critical points in phase transitions of various ...
Quantum Spin Chains And Luttinger Liquids With Junctions : Analytical And Numerical Studies
(2010-03-09)
We present in this thesis a series of studies on the physical properties of some one dimensional systems. In particular we study the low energy properties of various spin chains and a junction of Luttinger wires. For spin ...
Model Studies Of The Hot And Dense Strongly Interacting Matter
(2016-04-25)
Ultra-relativisitic heavy ion collisions produce quark gluon plasma-a hot and dense soup of deconfined quarks and gluons akin to the early universe. We study two models in the context of these collisions namely, Polyakov ...
