Liquid Drop Actuation by Photoelectrowetting
(2017)
In electrowetting an electric potential is applied between a droplet of electrolyte and a conductor separated by an insulator. The repulsion of like charges deforms and spreads the droplet until capillary and electric ...
Critical Mechanical Structures -Thermal Fluctuations and Self-Assembly
(2017)
Critical mechanical structures are structures on the verge of mechanical instability. Mechanical instability governs many fascinating phenomena in nature, including jamming, rigidity percolation, glass transitions, and ...
Surface and Bulk Transport of Samarium Hexaboride
(2017)
There has been a renewed interest in SmB6 during the past several years after the theoretical prediction that it is a topological Kondo insulator (TKI). Soon after, the conducting surface was experimentally discovered, ...
Mode Engineering of Single Photons from Cavity Spontaneous Parametric Down-Conversion Source and Quantum Dots
(2017)
Over the past decade, much effort has been made in identifying and characterizing systems that can form a building block of quantum networks, among which semiconductor quantum dots (QD) and spontaneous parametric down-conversion ...
High-Precision Spectroscopy Using Rydberg Atoms
(2017)
Using cold atoms, I probe the energy-level intervals between Rydberg states to high spectroscopic precision. The focus of this work is to lay the groundwork for an updated, highly-controlled measurement of the Rydberg ...
Laboratory Astrophysics Experiments to Study Star Formation
(2017)
As a thesis project, I devised and implemented a scaled accretion shock experiment on the OMEGA laser (Laboratory for Laser Energetics). This effort marked the first foray into the growing field of laser-created magnetized ...
Sterile Neutrino Dark Matter
(2017)
After reviewing the relevant background in cosmology and dark matter physics, we show that active neutrino masses and a keV-GeV mass sterile neutrino dark matter candidate can result from a modified, low energy see-saw ...
Structural Characterization Studies on Semiconducting ZnSnN2 Films using Synchrotron X-ray Diffraction
(2017)
This work is motivated by the need for new visible frequency direct bandgap semiconductor materials that are earth abundant and low-cost to meet the increasing demand for optoelectronic device applications such as solid ...
Nanoengineered Functional Structures for Photonic and Microfluidic Applications
(2017)
Owing to their extraordinary ability to interacting with external stimuli as well as their versatile functionalities hardly observed in bulk systems, micro- and nano-scale materials, structures, and phenomena have been the ...
Pattern Formation and Organization of Epithelial Tissues
(2017)
Developmental biology is a study of how elaborate patterns, shapes, and functions emerge as an organism grows and develops its body plan. From the physics point of view this is very much a self-organization process. The ...
