Title: Characterization and Control of Nuclear Spin Systems
Abstract: Liquid-state nuclear magnetic resonance (NMR) spectroscopy allows small quantum systems of coupled nuclear spins to be precisely controlled. This thesis examines three aspects of characterization and control of nuclear spins using liquid-...
[more]This project maps the stochastic and deterministic dynamics of open and closed quantum systems to analog circuit architectures and motifs. Such motifs may then be used to both map quantum systems to analog supercomputing chips, and to design novel quantum circuits. Many common circuit themes in analog and quantum computation include noise and thermodynamics, fault tolerance, feedback control, back action and loading, entanglement and correlation, precision measurement, nonlinear dynamics,...

Title: Challenges in Modeling Collisional and Turbulent Transport in Tokamak Fusion Plasmas (Video)
Abstract: One of the outstanding challenges in developing fusion as a practical energy source is improving energy confinement so that a large number of reactions take place. To do this will require reducing plasma transport by minimizing the heat fluxes out of the plasma. In the tokamak core,...
[more]Title: Solar Flares: Explosive Plasma Physics! (Video)
Abstract: Solar flares are among the most powerful explosions in the solar system. They cause strong variations in the EUV and X-ray output of the Sun, and in the radiative forcing of Earth's upper atmosphere. Their rate of occurrence follows the ~ 11 year solar activity cycle and they take place in active regions; the locations of strong...
[more]Title: Harnessing Quantum Systems with Long-Range Interactions (Video)
Abstract: Many AMO (atomic, molecular, and optical) systems, such as Rydberg atoms, polar molecules, and ions, exhibit long-range interactions decaying as a power-law with distance. In this talk, we will discuss the effects of long-range interactions on the speed of information propagation in quantum systems, with...
[more]Title: "Quantum Entanglement in Many-Body Systems and Boundary Theories" (Video)
Abstract: Entanglement are correlations between many quantum systems that cannot be described by classical theories. Entanglement is a key concept in quantum information theory and more recently it has been realized that it also has an important role in other areas of physics, from condensed matter and...
Title: Illuminating the Black Hole - Galaxy Connection (Video)
Abstract: Supermassive black holes, and the active galactic nuclei (AGN) that they power, are thought to play an integral role in the evolution of galaxies by acting to regulate, and eventually suppress, the star formation activity of their hosts. I will discuss recent efforts to test this proposed connection by studying the...
