      • Direct and Indirect Search for New Physics at Colliders 

        Lahiri, Jayita
        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 

        Sainadh, U Satya (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 ...
      • Efficient Quantum Algorithms for Linear Algebra Problems 

        Priyadarsini, Anjali V
        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 ...
      • Electronic Transport in Low-Dimensional Systems Quantum Dots, Quantum Wires And Topological Insulators 

        Soori, Abhiram (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 ...
      • Entanglement properties of gauge theories and the graviton. 

        Mukherjee, Jyotirmoy
        Entanglement entropy is emerging as a useful quantity to study critical phenomena in quantum systems, black holes physics, and holography. In this presentation, we discuss entanglement properties of gauge theories and ...
      • Explorations in Quantum Machine Learning 

        Khandelwal, Ankit
        Quantum Machine Learning is a rapidly developing field. In part 1 of this thesis, I benchmark common QML methods with the most popular datasets used in classical ML. I compare results from quantum and classical methods and ...
      • Explorations in the Space of S-Matrices 

        Haldar, Parthiv
        S-matrix is one of the fundamental observables of the quantum theory of relativistic particles. The quantum dynamics of relativistic particles can be abstractly understood in terms of S-matrix bypassing a Lagrangian ...
      • Exponential Resummation of QCD at Finite Chemical Potential 

        Mitra, Sabarnya
        A comprehensive study of the QCD phase diagram is one of the challenging and open problems in high energy physics. Having significant astrophysical implications, this is also important in constructing the chronological ...
      • Feynman Integral Calculus and Hypergeometric Functions: New Results, Interconnections and Computer Algebra 

        Bera, Souvik
        Feynman integrals play a fundamental role in perturbative calculations within the realm of quantum field theory. In this thesis, we study several important mathematical properties of multi-loop multi-leg Feynman Integrals ...
      • Flavor and Dark Matter Issues in Supersymmetric Models 

        Chowdhury, Debtosh (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 ...
      • Heavy flavour and direct photon probes of the gluon Sivers function 

        Kaushik, Abhiram B
        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 ...
      • The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider 

        Mohan, Kirtimaan A (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 ...
      • Higgs phenomenology and Dark Matter prospects in MSSM, NMSSM and U(1) extended SM 

        Barman, Rahool Kumar
        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) ...
      • Higher Spins, Entanglement Entropy And Holography 

        Datta, Shouvik (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 ...
      • Information scrambling in spin glasses and entanglement transition of monitored bosons 

        Yandoti, Venkata Lokesh Kumar
        In this thesis, I study various aspects of quantum many-body dynamics from the perspective of quantum information scrambling and entanglement dynamics in closed systems as well as systems interacting with the environment. ...
      • Issues in Phenomenology of Heavy Quarks And Leptons 

        Arunprasath, V (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 ...
      • Lessons for Conformal Field Theories from Bootstrap and Holography 

        Sen, Kallo (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 ...
      • Lessons for Gravity from Entanglement 

        Bhattacharyya, Arpan
        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 ...
      • Living on the Edge A Study of Boundary Modes In Two-dimensional Topological Systems 

        Seshadri, Ranjani
        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 ...
      • Mesonic screening mass at zero and finite chemical potential 

        Thakkar, Rishabh
        The finite temperature analysis of QCD is challenging since perturbation theory is not applicable in that regime. A non-perturbative method like lattice QCD is thus required to obtain an estimate of the necessary observables. ...
