Flexible spectral algorithms for simulating astrophysical and geophysical flows
(Massachusetts Institute of Technology, 2018)
Large-scale numerical simulations are key to studying the complex physical systems that surround us. Simulations provide the ability to perform simplified numerical experiments to build our understanding of large-scale ...
High-resolution studies of charge exchange in supernova remnants with Magellan, XMM-Newton, and Micro-X
(Massachusetts Institute of Technology, 2014)
Charge exchange, the semi-resonant transfer of an electron from a neutral atom to an excited state in an energetic ion, can occur in plasmas where energetic ions are incident on a cold, at least partially neutral gas. ...
CHAOS, holography, and other science
(Massachusetts Institute of Technology, 2016)
This thesis focuses on the relationship between black holes in holography, chaos in strongly-coupled quantum systems, and the computational complexity of holographic states. By directly considering the time evolution of ...
21 cm cosmology with optimized instrumentation and algorithms
(Massachusetts Institute of Technology, 2016)
Precision cosmology has made tremendous progress in the past two decades thanks to a large amount of high quality data from the Cosmic Microwave Background (CMB), galaxy surveys and other cosmological probes. However, most ...
It's always darkest before the cosmic dawn : early results from novel tools and telescopes for 21 cm cosmology
(Massachusetts Institute of Technology, 2015)
21 cm cosmology, the statistical observation of the high redshift universe using the hyperfine transition of neutral hydrogen, has the potential to revolutionize our understanding of cosmology and the astrophysical processes ...
Strong proton-photon interactions at the single-photon level
(Massachusetts Institute of Technology, 2015)
Engineering light at the single photon level is a long-standing goal in physics. In this thesis, we investigate optical nonlinearities at the single photon level orchestrated by an optical cavity. We demonstrate an all-optical ...
Charge transport in nanopatterned PbS colloidal quantum dot arrays
(Massachusetts Institute of Technology, 2015)
In this thesis, we study charge transport in nanopatterned arrays of PbS colloidal quantum dots using conventional two-probe measurements and an integrated charge sensor. PbS dots are synthesized in solution with an organic ...
Nonlinear optical and photoemission spectroscopies of quantum materials
(Massachusetts Institute of Technology, 2018)
Quantum materials are characterized by a macroscopic behavior that does not have a clear classical counterpart. Among the experimental probes capable of exploring the exotic properties of quantum materials, ultrafast laser ...
Analysis of vacuum and argon gas fill data from the MiniCLEAN dark matter experiment
(Massachusetts Institute of Technology, 2015)
The existence of particle dark matter provides a consistent framework for understanding many astronomical observations. The rotation curves of galaxies and galaxyclusters, for example, indicate the majority of mass in these ...
Using time-resolved nuclear diagnostics to probe kinetic/multi-ion physics and shock dynamics on OMEGA and the NIF
(Massachusetts Institute of Technology, 2018)
This thesis focuses on the development and application of time-resolved nuclear diagnostics to probe plasma evolution in Inertial Confinement Fusion (ICF) implosions. On the OMEGA laser facility at the Laboratory for Laser ...
