Title: Fast Wavefront Characterization of Optical Traps for Quantum Gases
Abstract: Ultracold quantum gases are frequently confined in optical dipole traps consisting of focused high power laser beams. In this project, we have designed and built a dynamically controllable dipole trap in which...

Title: Fabrication and Characterization of Graphene Devices
Abstract: Graphene is a one-atom-thick 2D crystal of carbon atoms that form a hexagonal lattice. As a consequence of this structure, graphene has a linear energy dispersion relation about the Dirac point where the valence and conduction bands meet...

Title: The Wigner Flow Function for Open Quantum Systems
Abstract: In classical mechanics, one can fully describe the dynamics of any one-dimensional system using a single trajectory in phase space. Since the rules of quantum mechanics beget an inherent uncertainty associated with a simultaneous measurement of the...
[more]Dartmouth post-doc Alexa Halford's latest paper using BARREL data is highlighted in a NASA article. BARREL was designed to study how electrons from Earth’s radiation belts – vast swaths of particles trapped in Earth’s magnetic field hundreds of miles above the surface – can make their way down into the atmosphere. The BARREL campaign is primarily tasked with supplementing...

Title: Zonal Wind Variability of the Jovian Planets
Abstract:
The proximity and massive scale of Jupiter has made it a uniquely observable case study in planetary atmospheric dynamics, resulting in a wealth of data from several missions. Jupiter’s characteristically striated atmosphere makes it a prime...

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,...
