Kavli Affiliate: Andrei Faraon | First 5 Authors: Andrei Faraon, Jelena Vuckovic, , , | Summary: We demonstrate a method to locally control the temperature of photonic crystal devices via micron-scale electrical heaters. The method is used to control the resonant frequency of InAs quantum dots strongly coupled to GaAs photonic crystal resonators. This technique […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Samir Garzon, Richard A. Webb, Mark Covington, Shehzaad Kaka, Thomas M. Crawford | Summary: In large magnetoresistance devices spin torque-induced changes in resistance can produce GHz current and voltage oscillations which can affect magnetization reversal. In addition, capacitive shunting in large resistance devices can further reduce […]
Kavli Affiliate: Karen L. Byrum | First 5 Authors: Robert G. Wagner, Karen L. Byrum, Mayly Sanchez, Alexandre V. Vaniachine, Oswald Siegmund | Summary: We advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino astronomy, and direct dark matter detectors. […]
Kavli Affiliate: Ralf Heilmann | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that this emission was of thermal nature […]
Kavli Affiliate: Mark Schattenburg | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemical evolution in the Galaxy […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Joshua A. Frieman, , , , | Summary: The discovery ten years ago that the expansion of the Universe is accelerating put in place the present cosmological model, in which the Universe is composed of 4% baryons, 20% dark matter, and 76% dark energy. Yet the […]
