Narrated by Liam Neeson, black holes are among the most mysterious and exotic objects in the Universe. These dark beasts are one of a few phenomenon out in the cosmos where the known laws of physics and general relativity break down. Black Holes: The Other Side of Infinity explores the power and grace of these cosmic beasts.
Abstract: X-rays provide a unique spectroscopic view of molecules and
materials, from an element-specific and orbital-selective frame of
reference. Femtosecond and attosecond X-ray and extreme ultraviolet pulses
(XUV) are used to probe curve crossings and conical intersections in
molecules, electron and hole carriers in solids, coherent phonon motions,
and core hole excitons, revealing breathtaking 'movies' of novel, ultrashort
dynamical processes.

Abstract: Point defects in crystals are the solid state analog to trapped ions. Thus these “quantum defects”, which can be integrated into solid-state devices, have gained popularity as qubit candidates for scalable quantum networks. In this talk, I will introduce some of the basic quantum defect properties desirable for quantum network applications.

Abstract:
Hybrid quantum networks rely on faithful quantum state transfer between disparate physics elements operating at dissimilar frequencies. Quantum frequency conversion bridges their frequency gaps by coherently manipulating the carrier frequency while maintaining the quantum correlations. The efficiency of frequency conversion is dictated by photon-photon interaction in a nonlinear optical media which is typically weak.
This colloquium is in-person and online.

Abstract: Magnetospheric physics has a massive problem: we have not yet determined the fundamental processes that govern plasma mass and energy flow through the terrestrial magnetosphere, nor the degree to which these flows regulate key magnetospheric subsystems. Knowledge of these processes is critical to understanding the mass loss rate of Earth’s atmosphere, as well as for determining the role that a planetary magnetic field plays in atmospheric retention, and therefore habitability, for Earth-like planets beyond the solar system.
