New Methods for Terahertz and Ultrafast Infrared Spectroscopy of Biological Materials and Graphene Buffer Layer
(2019)
The development of advanced optical spectroscopy has always been a frontier in optics and material science. This dissertation develops several new methods for terahertz (THz) and infrared spectroscopy and presents their ...
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 ...
Characterization of X-Pinches on the MAIZE Linear Transformer Driver
(2023)
An X-pinch, formed by driving an intense current pulse (>100 kA in ~100 ns) through the
crossing of 2 or more wires, can result in the formation of a small radius, runaway compressional micro-pinch. A micro-pinch is ...
Multi-Wavelength Facets of Galaxy Clusters
(2018)
Cluster cosmology, as investigated by the number counts method, is deeply linked to the constituent properties of our Universe and small-scale astrophysical phenomena. In the number counts method, a key challenge is relating ...
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 ...
The N=4 SU(N) Super-Yang-Mills Index and Dual AdS Black Holes
(2021)
The main subjects of this dissertation are indices of the N=4 SU(N) Super-Yang-Mills (SYM) theory, namely the topologically twisted index and the superconformal index. These indices have received a lot of attention since ...
Interactions Between Fluorescent Molecules and Plasmonic Nanoparticles: A Super-Resolution Study
(2017)
Single-molecule super-resolution imaging techniques play an increasingly important role in studying complex fine structures, dynamics and interactions in nanoscale confined spaces. The resolution of this technique can be ...
Probing Heat Transport and Energy Conversion at the Atomic and Single Molecule Scale
(2018)
The study of heat transport and energy conversion constitutes an important subject in modern physics and engineering research. The widely-applied Fourier’s and Planck’s laws have proven to be very useful to describe heat ...
Electron Acceleration and Radiation Generation from Relativistic Laser-Plasma Interactions and Statistical Methods at High Repetition-Rate
(2021)
This dissertation explores the interaction between high-intensity lasers and plasmas to accelerate electrons and produce radiation via experimental and computational efforts. The laser pulses used in this dissertation have ...
Information Processing under Physiological Pulsatile Stimulation in a G-protein Coupled Signaling Pathway
(2016)
The cellular microenvironment is often dynamic, and several physiological ligands are released in pulsatile bursts. The main hypothesis driving this study is that cells are able to discern these time-varying dynamic inputs ...
