Abstract: The creation of a matter-wave interferometer can be achieved by loading Bose-Einstein condensed atoms into a crystal of light formed by interfering laser beams. By translating this optical lattice in a specific way, the traditional steps of interferometry can all be implemented, i.e., splitting, propagating, reflecting, and recombining the quantum wavefunction. Using this concept, we have designed and built a compact device to sense inertial signals, including accelerations, rotations, gravity, and gravity gradients.

Abstract: Imagine if the act of looking at an object caused it to move – or imagine you had a pair of dice that always rolled doubles, but of different numbers each roll. These counterintuitive phenomena are commonplace in the realm of quantum mechanics, which describes systems that are generally very small, very cold, and/or very isolated from the rest of the world.

Reception at 5:30 at the Sink. We'll meet at the hbar at 5:15 to head over.

Abstract: Tremendous new insights into the Martian atmosphere have been achieved in recent years by two ultraviolet spectrographs built at LASP: the Imaging Ultraviolet Spectrograph (IUVS) aboard the Mars Atmospheric and Volatile EvolutioN (MAVEN) mission, and the Emirates Mars Ultraviolet Spectrometer (EMUS) aboard the Emirates Mars Mission (EMM). Both instruments have far exceeded their design goals in science return.

 Ultracold dipolar atoms and molecules present a wealth of exciting out-of-equilibrium phenomena. I’ll discuss some of the understanding developed over the past several years, and several useful applications to experiments.

Abstract: Living systems exhibit unique emergent properties such as self-assembly, rigidity, resilience, and robustness.

Abstract: Polarons, quasiparticles composed of an electronic excitation and the material deformation these cause in a solid or liquid, are ubiquitous. Understanding and controlling their formation, nonequilibrium relaxation, and motion are essential in developing next-generation photocatalysts, energy conversion devices, and even superconductors. In this talk, I introduce some of our recent theoretical advances that enable us to probe the exact quantum dynamics of Holstein polarons subject to dispersive phonon baths in small lattice models to the thermodynamic limit.

Abstract: NASA Earth Science has put significant attention towards enabling uses of Earth science information to support decision making activities by public and private sector organizations. In addition to supporting technical innovations, NASA also pursued several programmatic innovations to help the Earth science community develop capacity in engaging with users, designing projects, and enabling results.

APS Faculty who have research opportunities in their group will present flash talks on their research.

Abstract:

Absract: The promising optoelectronic properties of halide perovskites position them as candidate materials for solar cells, displays, and more. Their compositional and process flexibility provides a large and attractive design space and has led to outstanding optoelectronic figures of merit. However, the same flexibility also gives rise to challenges in reproducibility and phase stability.

Abstract: Fundamental understanding of the climate responses to solar variability is obscured by the large and complex climate variability. This long-standing issue is addressed here by examining climate responses under an extreme quiet sun (EQS) scenario, obtained by making the sun void of all magnetic fields. It is used to drive a coupled climate model with whole atmosphere and ocean components.
