Spatial Nonlocality and Its Effects on the Scattering Characteristics of Wave-Bearing Media
(2022)
Reciprocity is the principle in the study of wave propagation that states that given a source and a receiver in a linear domain, switching their locations will not affect the received signal. Systems that break reciprocity ...
Dynamical Constraints of Galaxy Clusters via Spectroscopic Observations
(2020)
Galaxy Clusters are the largest gravitationally bound objects in the Universe, residing at the boundary between the expansive push of dark energy in the vacuum and the attractive pull of dark matter the fills the halo in ...
Rigidity and Elasticity beyond Isostaticity
(2021)
Isotatic mechanical structures, where numbers of constraints arising from physical interactions balance the number of internal degrees of freedom, are on the verge of mechanical instability. Isostatic structures exhibit ...
The Study of Exciton-Polariton Phase Transitions Through Spontaneous Vortices and First-Order Correlation
(2020)
Phase transitions are among the most fascinating phenomena discovered in the last century, with collective molecular dynamics leading to novel observations such as superconductivity and superfluidity. Yet even in the ...
Nonequilibrium Dynamics of Strongly Correlated Systems
(2021)
In this thesis, we describe methods for solving quantum impurity models out of equilibrium, and consider several applications of these methods.
Quantum impurity models describe systems in which a small subsystem (the ...
Kinetic Theory of Strongly Magnetized Plasmas
(2023)
Coulomb collisions in plasmas are typically modeled using the Boltzmann collision operator or its variants. These apply to weakly magnetized plasmas in which the typical gyroradius of particles significantly exceeds the ...
Probing Dynamic Excitations in Novel Quantum Magnets Using Raman Spectroscopy
(2021)
Quantum materials are a class of materials where charge, orbit, spin, and lattice degrees of freedoms (DOFs) entangle to give rise to novel phases. A major subset of quantum materials, quantum magnets, span a broad spectrum ...
Explorations in Quantum Gravity: Holography and AdS Black Holes
(2022)
This thesis explores a series of topics in quantum gravity with a focus on the quantum nature of AdS black holes via the AdS/CFT correspondence. In Part I, we examine various holographic approaches to AdS black hole entropy, ...
Quantum Light Scattering in Disordered and Structured Media
(2021)
Understanding the complex interactions of the quantum light with different media provides valuable insights into potential applications in quantum tomography, microscopy, circuit and network design, and imaging. This thesis ...
Light Matter Interfaces with Single-Atom Arrays and Rydberg Ensembles
(2022)
A principal goal of distributed quantum processing is the ability to generate, manipulate, and transfer quantum states between distant nodes of a quantum network. These protocols generally require connecting photonic and ...
