Relativistic and Non-Relativistic Holography
… principle and renormalization problems in non-relativistic holography. The systematic boundary condition formalism of Skenderis and Van Rees is extended to scalar field in Schr¨odinger space-time. In the same background, variational principle and renormalization procedures are constructed …

RELATIVISTIC QUANTUM CRYPTOGRAPHY
In this thesis we explore the benefits of relativistic constraints for cryptography. We first revisit non-communicating models and its applications in the context of interactive proofs and cryptography. We propose bit commitment protocols whose security hinges on communication constraints and …

Relativistic Quantum Tasks
… we study the behaviour of quantum information in relativistic spacetime. The field of quantum information arose from the realisation that quantum information has a number of crucial properties that distinguish it from classical information, such as the no-cloning property, quantum contextuality, …

Integrable Nonlinear Relativistic Equations
This work focuses on three nonlinear relativistic equations: the symmetric Chiral field equation, Einstein's field equation for metrics with two commuting Killing vectors and Einstein's field equation for diagonal metrics that depend on three variables. The symmetric Chiral field equation is …

Spectral properties of relativistic and non-relativistic Krönig- Penney Hamiltonians with short-range impurities
… work, we investigate the spectrum of the non-relativistic Krönig-Penney Hamiltonian H<sub>α</sub>= -d²/dx² +αΣ<sub>m∈Z</sub>δ(-(2m+1)π) perturbed by a short-range potential λW and the spectrum of its relativistic counterpart obtained by replacing the Schrödinger Hamiltonian H<sub>α</sub> with …

Interfaces in Numerical Relativistic hydrodynamics
… for modelling sharp interfaces<br/>between relativistic fluids. The motivation for this work lies in obtaining accurate<br/>models of neutron star interiors for use in multidimensional simulations<br/>in general relativity. The interior structure of a neutron star is believed to<br/>contain …

Simulations of Dynamic Relativistic Magnetospheres
… irrelevant. In this vanishing-inertia---or ultra-relativistic---limit, magnetohydrodynamics becomes force-free electrodynamics, a system of equations comprising only the magnetic and electric fields, and in which the plasma response is effected by a nonlinear current density term. In this …

Dynamical studies in relativistic cosmology
We conduct three investigations in Relativistic Cosmology that is the Einstein Field Equations applied to the largest scales with source field typically taken to be a perfect fluid and fundamental observers comoving with the preferred fluid four-velocity. We show using a tetrad analysis of the …

Non-Relativistic Holography from Horava Gravity
… coupled field theories are those of a non-relativistic nature that arise in condensed matter systems. Herein, motivated by the generic symmetry structure of these theories, a non-relativistic version of holography is proposed using an alternate theory of gravity, Horava gravity. …

A Relativistic Model for Heavy Mesons
… we construct a model for heavy mesons based on a relativistic bound state wave equation, the Gross equation. The kernel we use is based on scalar confining and vector Coulomb potentials. Wave functions are treated to leading order and energies to order 1/<sub>MQ</sub> in the heavy-light systems, …

Causal and stable stochastic relativistic hydrodynamics
… on causal and stable formulations of stochastic relativistic hydrodynamics. Connections between causality, stability, and the foliation independence of equal-time fluctuations are used to formulate stochastic hydrodynamics in the linear regime. This approach is applied to several conventional …

Security Protocols in Relativistic Quantum Cryptography
This thesis explores quantum cryptographic protocols designed to provide secure implementation of three key tasks, through mathematical analysis and qualitative discussion. Each chapter focuses on a distinct cryptographic scheme and explores its utility relative to classical and alternative quantum …

Relativistic corrections to weak lensing convergence
A fundamental issue in modern science is the dark energy problem - the apparent accelerating expansion of the universe. Many cosmological observations of the Cosmic Microwave Background (CMB), Baryon Acoustic Oscillation (BAO) and weak lensing have been carried out to try to understand the nature …

Holographic view of non-relativistic physics
Motivated by the AdS/CFT correspondence for relativistic CFTs, it seems natural to generalize it to non-relativistic CFTs. Such a dual description could provide insight into strong coupling phenomena observed in condensed matter systems. Scale invariance can be realized in non-relativistic theories …

Relativistic quantum field in theoretical physics
Quantum field theory is the most well-developed tool in theoretical physics to study about the dynamics at microscopic scales, with particles and quantum behaviors. In this thesis I'll review about the construction of quantum field theory from the S-matrix point of view (building up particles and …
