Topological Mechanical Systems Beyond the Limit of Linear Ideal Springs
(2022)
In recent years, topological mechanical metamaterials (TMM) have gradually attracted attention across different disciplines including physics, mechanical engineering, and materials science. It has achieved great success ...
Phase Transitions of Exciton-Polaritons in Grating-Based Microcavities
(2022)
Exciton-polaritons in semiconductor microcavities have been a platform to study macroscopic quantum phenomena. They exhibit phases like Bose–Einstein condensate (BEC) and conventional photon lasing. Due to their fermionic ...
Analysis of the Coupled Electron and Nuclear Spin Systems from Optically Induced Dynamic Nuclear Polarization in GaAs
(2022)
Gallium arsenide (GaAs) is a semiconductor that possesses a direct band gap whose optical transitions are spin selective. This property is ideal for investigation into optical generation and detection of electron spins, ...
Effects of Pre-Ionization on the Gas-Puff Z-Pinch
(2022)
This dissertation presents: (1) the development of a gas-puff z-pinch system for the MAIZE pulsed power facility; (2) experiments carried out to characterize the system’s performance on MAIZE; and (3) experiments to test ...
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 ...
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, ...
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 ...
Fluorine-Enhanced Room Temperature Luminescence of Er-Doped Crystalline Silicon
(Wiley Periodicals, Inc., 2022-12)
Ionic Conductive and Highly‐Stable Interface for Alkali Metal Anodes
(Wiley Periodicals, Inc., 2022-08)
Alkali metals are regarded as the most promising candidates for advanced anode for the next‐generation batteries due to their high specific capacity, low electrochemical potential, and lightweight. However, critical problems ...
Effect of Nanoscale Confinement on Ultrafast Dynamics of Singlet Fission in TIPS-Pentacene
(WILEY-VCH, 2022-11-18)
Singlet fission (SF) is a phenomenon for the generation of a pair of triplet excitons from anexcited molecule in singlet electronic state interacting with another adjacent molecule in its ground electronic state. By ...
