This collection contains some of the theses and dissertations produced by students in the University of Oregon Physics Graduate Program. Paper copies of these and other dissertations and theses are available through the UO Libraries.
Integrated quantum information technologies such as photonic circuits, quantum transducers, and magnetic sensors require robust single-photon sources in precise locations. Solid-state single photon emitters (SPEs) hosted ...
Gravitational Waves (GWs) have quickly emerged as powerful, indispensabletools for studying gravity in the strong field regime and high-energy astrophysical
phenomena since they were first directly detected by the Laser ...
The discovery of the Higgs boson confirmed that the Standard Model is the correct description of nature below some high energy scale. However, we know the Standard Model is incomplete and have yet to find significant ...

Long-range dispersal of offspring is ubiquitous in nature, from seeds that disperse random distances thanks to being carried by animals, to pollen that gets carried long distances by the wind, and even viruses that spread ...

Networks of nanoelectromechanical (NEMS) resonators are useful analogs for a variety of many- body systems and enable impactful applications in sensing, phononics, and mechanical information processing. Two main challenges ...
The third observing run of Advanced LIGO and Virgo (O3) took place fromApril 1st, 2019 to September 30th, 2019, and from November 1st, 2019 to March
27th, 2020. The multi-messenger astronomy efforts during O3 included ...

This dissertation presents the development of a boosted analysis in the searchfor the resonant production of a new heavy scalar X decaying to two Higgs bosons,
which is predicted by some Beyond the Standard Model theories. ...
The viability of quantum computers depends on the development of scalable platforms with low error rates. Our "Oregon Ions" group has studied one such scalable architecture proposal including the limitations placed on logic ...
Collectively, a colony of ants can execute complex and highly organized behaviors, not least of which is the formation of ant ‘paths’ - the steady bidirectional flow of individuals and resources that provides the colony ...
Thin elastic shells are ubiquitous in nature. Indentation measurements (i.e., poking) provide a useful way for probing mechanical properties of these shell structures.
While spherical and cylindrical shells made of isotropic ...
For well over a century, neuroscientists have been studying the inherent ties between neuronal morphology and functionality. Santiago Ramón y Cajal, in his work that ultimately awarded him a Nobel Prize in 1906, established ...
The global market for power solely for data center usage is estimated to be $12.4 billion by 2027[1]. In 2021, data center electricity consumption was ∼400 TW h, representing almost 2% of the global energy demand[2]. Ongoing ...
This dissertation presents two searches for signals of dark matter in an integrated luminosity of 139 ifb of proton-proton collision data collected at a center of mass energy of $\sqrt{s}$ = 13 TeV with the ATLAS detector ...
Silicon vacancy centers (SiVs) in diamond are local defects in the diamond lattice that behave as atomic-like systems with electronic energy levels and optical transitions. The SiV's optical properties and long spin ...
We investigate the role of time-frequency entanglement in nonlinear interactions of both low- and high-gain broadband squeezed vacuum. Our work is motivated by the large body of research proposing the use of time-frequency ...
In this dissertation we study the interaction of a single atom with a single mode of the electromagnetic field in an optical cavity. We emphasize strong coupling conditions, where the dipole coupling strength is larger ...

Animal intestines harbor hundreds of microbial species that play a crucial role in host health and development. Despite their importance, many questions about the rules that govern community assembly in these complex ...
Nguyen, Philippe(University of Oregon, 2022-10-26)
This dissertation describes methods used for characterizing the sources and effects of environmental noise in Advanced LIGO detectors from the end of the second LIGO-Virgo observing run through the end of the third observing ...
Kilgallon, Aaron(University of Oregon, 2022-10-26)
A search for emerging jets in the dijet topology is presented here using 139 ifb of √s = 13 TeV Run 2 ATLAS proton-proton collision data. Emerging jets constitute a class of dark jet models that have long-lived hadronization ...
The search for physics beyond the Standard Model is a daunting task. As parameter spaces for compelling models shrink, there is motivation for more radical concepts. However, there is a need for understanding the structure ...
