Testing the limits of nonlocality
… are classically impossible. The phenomenon of nonlocality is fundamental to this study, and polarization-entangled photons o er a clean, bright, and stable system for its experimental investigation. This thesis investigates, both experimentally and theoretically, the creation, manipulation, and …

Quantum nonlocality: an analysis of the implications of Bell's Theorem and quantum correlations for nonlocality.
… conditions. So to understand the nature of nonlocality in EPR, we first need to understand the conceptual relations between factorizability, these various locality conditions and the nature of the quantum correlations. That is the main focus of my thesis. My main conclusion is that these …

Advanced tests of nonlocality with entangled photons
… applications. Not only do we demonstrate that nonlocality must exist, but we begin an experimental exploration in an attempt to understand and quantify this nonlocality. We do so by considering all theories that obey no-signaling (or relativistic causality). In our experiments, we observe the …

Characterization of quantum states: advances in quantum tomography and tests of nonlocality
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-04-06 without embargo terms

Improving the Dispersive Optical Model toward a Dispersive Self-energy Method
… parametrizations. The explicit treatment of nonlocality allows for a proper solution of the Dyson equation, and the resulting propagator can then be used to calculate experimental observables associated with ground state properties, such as the charge density, particle number, and the energy …

Nonlocal correlations between freely propagating pairs of atoms
… technical requirements in the test of quantum nonlocality however, experimentalists have only recently demonstrated the nonlocal nature of quantum mechanics. Such well-controlled physical systems were few just a decade ago. This thesis contributes to the exponentially growing diversity of …

Stability of Periodic Waves in Nonlocal Dispersive Equations
… Nonlinear Schrodinger Equation, where the nonlocality of the fractional Laplacian presents formidable analytical challenges and elicits the development of functional-analytic tools to complement the absence of more-understood techniques commonly used to analyze local equations. Further, we …

Bounding the Quantum and Classical Resources in Bell Experiments
Bell's theory of nonlocality in quantum mechanics allows for interesting correlations between separated parties. In this scenario, both parties share a quantum state and measure it to obtain a classical value. Through entanglement, the results of the measurement from one party can affect the …

Modeling of nano-scale fracture mechanisms in a graphene sheet using the atomistic j-integral
… length-scale. In addition, effects such as nonlocality in molecular dynamics (MD) computations and entropic effects at the atomistic scale add to the discrepancy with LEFM. The fracture study on crystalline (graphene) was performed to lay the foundation for atomistic predictions of fracture …

Relativistic Hamiltonians and short range structure of nuclei
… is reduced by rv 15% by the relativistic nonlocality, which may also have significant effects on pion exchange currents. However, almost all of this reduction is canceled by changes in the kinetic energy and other interaction terms, and the total effect of the nonlocalities on the binding …

Multiscale Peridynamics Analysis of Nanocomposites and Energetic Materials Using Nonlocal and Local Interface Models
… bonds and therefore defines the extent of nonlocality. Peridynamics has different formulations regarding the bond interactions. A bond-based peridynamics framework is used here. A verified and validated in-house code is used for the simulations. The simulations for the carbon nanotube and …

Quantum theory from the perspective of general probabilistic theories
… Particular attention is given to quantum nonlocality, and its interaction with areas of physical and mathematical interest such as entropy, reversible dynamics, information-based games and the idea of negative probability. We begin with a review of non-signaling distributions and convex …

Optical quantum random number generation: applications of single-photon event timing
