#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 ...

#### 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 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) ...

#### 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 ...
