In this colloquium we will describe the mission, goals and the partnership strengths of the new SQMS Center. SQMS brings the power of DOE laboratories, together with industry, academia and other federal entities, to achieve transformational advances in the major cross-cutting challenge of understanding and eliminating the decoherence mechanisms in superconducting 2D and 3D devices, with the final goal of enabling construction and deployment of superior quantum systems for computing and sensing.
For nearly two decades the Hubble Space Telescope has been heavily used to locate supernovae in high redshift environments, with the primary goal of improving constraints on the nature of dark energy. Along the way we have made surprising observations on the nature of supernovae themselves, and clues to their elusive progenitor mechanisms, some of which are difficult to reconcile with observations at much lower redshift.
Thermoelectric materials are important for spacecraft power, waste heat recovery, thermal management and cooling applications. Here I discuss the basic physics of thermoelectric effects and approaches for discovering new thermoelectric materials. A key issue is the contraindication of high thermoelectric performance, which places thermoelectrics into an interesting group of materials that includes transparent conductors, magnetic semiconductors and multiferroics. The efficiency of thermoelectric systems is limited by materials performance.
