Explorations in the Space of S-Matrices
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 ...
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 ...
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 ...
Lessons for Conformal Field Theories from Bootstrap and Holography
(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 ...
Novel Pathways for Beyond Standard Model Physics
In the light of discovering the Higgs boson and null results at the LHC, we look for new pathways
for Beyond Standard Model Physics, which could accommodate at least one of the Standard Model
shortcomings. (i) Unification ...
Aspects of Holography and Quantum complexity
We begin with the Principle of holography and the AdS/CFT correspondence. We begin our investigations by considering the Principle of Holography, at the level of codimension-1 screens. We argue that the mechanism of encoding ...
