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 ... -
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 ... -
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 ... -
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 ... -
Electronic Transport in Low-Dimensional Systems Quantum Dots, Quantum Wires And Topological Insulators
(2018-04-05)This thesis presents the work done on electronic transport in various interacting and non-interacting systems in one and two dimensions. The systems under study are: an interacting quantum dot [1], a non-interacting quantum ... -
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 ... -
The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider
(2018-05-08)The nature of interactions of fundamental particles is governed by symmetries. These interactions are well described by an elegant and simple SU(3)c x SU(2)L x U(1)Y symmetric gauge theory that we call the Standard Model ... -
Higher Spins, Entanglement Entropy And Holography
(2017-08-21)The idea of holography [1, 2] finds a concrete realization in form of the AdS/CFT correspondence [3, 4]. This duality relates a field theory with conformal symmetries to quantum gravity living in one higher dimension. In ... -
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 ... -
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, ... -
Search for dark matter produced in association with b-jets in proton-proton collisions at √s = 13 TeV with the CMS detector using full Run2 data
A search for dark matter particles in the events containing large missing transverse energy accompanied by b-quarks has been performed. The data collected by the Compact Muon Solenoid detector at the Large Hadron Collider ... -
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) ... -
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 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 ...
