  • Title: Gamma-Ray Polarimetry as a Probe of the Central Engine of Gamma-Ray Bursts (Video)

    Abstract: Discovered nearly forty years ago, gamma-ray bursts (GRBs) are brief, intense flashes of gamma-rays appearing randomly across the sky at a measurable rate of about once per day. Now known to originate at cosmological distances, they are the most luminous objects in the universe.  It has been...

  • Title: Physical Oceanography - Perspective, Fundamentals & Cool Stuff (Video)

    Abstract: This presentation will begin by comparing progress in physical oceanography with that in particle physics, highlighting some of the aspects that make physical oceanography difficult to study.  This will be followed with a brief introduction to the fundamental concepts in physical oceanography – done in...

  • Title: Exoplanets: Under a Microscope, and Through a Wide-Field Lens  (Video)

    Abstract: The Solar System furnishes the most familiar planetary architecture: many planets, orbiting nearly coplanar to one another. We can examine the composition and atmospheres of the Solar System planets in detail, even occasionally in situ. Studies of planets orbiting other stars (exoplanets), in contrast, only...

  • Title: Tying Knots in a Quantum Fluid (Video)

    Abstract: Knots are familiar entities that appear at a captivating nexus of art, technology, mathematics,and science. Following a lengthy period of theoretical investigation and development, they have recently attracted great experimental interest in contexts ranging from knotted DNA and nanostructures to vortex knots in classical fluids. In this...

  • Title: The Tonks-Girardeau Gas: Then, Now, and in the Future (Video)

    Abstract: In this presentation, I will review the 55+ years of progress passed since Marvin Girardeau found, in 1960, a full nonperturbative solution for the quantum hard-core bosons, further extended to the finite strength interactions in 1963 by Lieb and Liniger. This discovery brought the multi-(all the way to infinite-)...

    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...

  • 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...
