The unification of quantum mechanics and general relativity is the holy grail of fundamental theoretical physics. This thesis represents a small part of that effort, …
A new non-perturbative, gauge-invariant, exact, finite model of quantum chromody- namics, with a particular choice of renormalization is applied to high energy elastic pp- scattering. …
We study several aspects of high energy scattering using the AdS/CFT correspondence.We begin with concise theoretical overviews of a few relevant topics. First is a …
In recent years there have been significant progresses in the understanding of scattering amplitudes at both strong and weak coupling. There are new dualities discovered, …
In this thesis we present studies of scattering amplitudes on the celestial sphere at null infinity (celestial amplitudes), the cluster adjacency structure of scattering amplitudes …
Scattering amplitudes have undergone considerable study in the last few years. Much of the progress has come from abandoning Feynman diagram techniques and instead exploring …
The Giant Spin Hall Effect (GSHE) in certain transition metals due to strong spin-orbit interaction has shown great potential in the development of novel spintronic …
Moore’s law, which has governed semiconductor technology for decades, has been increasingly challenged in recent years. Rather than relying on electron charge currents, spintronics-based logic …
Nonperturbative issues in quantum gravity in Anti de Sitter spacetimes are addressed by means of the manifestly holographic framework of Anti de Sitter/Conformal Field theory …
Abstract of Holographic Techniques for Strongly Coupled Scattering, by Timothy Gillooly Raben, Ph.D., Brown University, May 2016. Quarks and gluons have historically been difficult to …
This thesis is concerned with understanding features of holography in de-Sitter (dS) and Minkowski space. We give bulk-boundary mapping in dS at large N using …
This work studies the analytical structure of scattering amplitudes in a class of toy models, from the perspective of novel geometrical structures underlying scattering amplitudes, …
In this work we present our contribution to the method of using Landau singularities for probing scattering amplitudes in planar massless quantum field theories. We …
The representation theory of supersymmetry is further developed, starting from questions about the role of the symmetric group in 1D, N-extended supersymmetry and the construction …
The main subject of this thesis is scattering amplitudes in N=4 super-Yang-Mills theory (SYM) and N=8 super-gravity theory (SUGRA). We study several aspects of the …
We study scattering amplitudes in N=4 SYM, holographic models of four-dimensional flat-space scattering amplitudes in terms of two-dimensional conformal fields theories dubbed celestial CFTs (CCFT), …
This thesis is concerned with computation of tree-level scattering amplitudes through scattering equations and derivation of soft theorems from them. Additionally, mapping of scattering amplitudes …
A search for microscopic black hole production and decay in proton-proton collisions at a center-of-mass energy of 7 TeV has been conducted using Compact Muon …
In this thesis, we present a study of the singularity structure of scattering amplitudes in maximally supersymmetric Yang-Mills (N=4 SYM). We first consider the cluster …
The AdS/CFT correspondence offers a unique possibility for the nonperturbative investigation of gauge theories, through their conjectured equivalence to string theories. In the past years, …
