Photoionization of Cold Atoms and Non-Neutral Plasma Dynamics
(2021)
The development of atom trapping and cooling techniques has been a boon for the field of low temperature plasma physics. By forming plasmas through photoionization (PI) of cold atoms, researchers are able to create cold, ...
Direct and Indirect Searches for Axion Dark Matter
(2021)
The majority of the matter in the Universe is non-luminous and unaccounted for by any known particle, making the unknown nature of dark matter one of the most urgent problems in fundamental physics. Amidst a broad landscape ...
A Nanoscale Blueprint of the Human Kinetochore and the Functional Limits of Its Design
(2021)
Cellular duplication is the cornerstone of all life, allowing organisms to replicate and develop through the creation of genetically identical cells. Proper duplication requires cells to accurately segregate copies of their ...
Electromagnetic Field Sensing with Rydberg Atoms in Vapor Cells
(2021)
Research of hot atomic vapor systems has a long history. Recently, much-improved technologies, such as lasers, microwaves and digital/analog control systems, have led to exciting progress in this reviving field. Due to its ...
Dynamics of the Jovian Magnetosphere: Combining Insights from Global MHD Simulations and In Situ Measurements From the Juno Spacecraft
(2021)
Unlike the terrestrial magnetosphere, which responds strongly to changes in the solar wind and interplanetary magnetic field, Jupiter's magnetosphere depends largely on internal processes related to its strong planetary ...
Next Generation Graphene Photonics Enabled by Ultrafast Light-Matter Interactions and Machine Learning
(2021)
Graphene was first experimentally studied in 2004, featuring an atomically-thin structure. Since then, many unique photonic and electrical properties of graphene and other 2D materials were reported. However, additional ...
Bootstrapping Scattering Amplitudes in Effective Field Theories
(2021)
The modern approach to scattering amplitudes has provided a plethora of techniques that allow us to circumvent Lagrangians and Feynman rules. The bootstrap of amplitudes in quantum field theories allows us to study the ...
Searching for Beyond the Standard Model Physics with Photon Final States
(2021)
The Standard Model, while remarkably successful at predicting phenomena down to length scales of 10^−17 cm, is an incomplete theory, failing to account for several experimentally observed phenomena. The search for new ...
Composite Spin Hall Conductivity from Non-collinear Antiferromagnetic Order in PtMn3
(2021)
Thin film antiferromagnets have emerged as strong candidates for state-of-the-art spintronic applications, promising efficient spin current generation that is critical for the development of low power non-volatile electronics. ...
Wave Propagation and Source Localization in Random and Refracting Media
(2021)
This thesis focuses on understanding the way that acoustic and electromagnetic waves propagate through an inhomogeneous or turbulent environment, and analyzes the effect that this uncertainty has on signal processing ...
