Kavli Affiliate: Alan Levine | First 5 Authors: Martin Durant, Remon Cornelisse, Ron Remillard, Alan Levine, | Summary: Regular observations by the All Sky Monitor aboard the Rossi X-ray Timing Explorer satellite have yielded well-sampled light-curves with a time baseline of over ten years. We find that up to eight of the sixteen brightest persistent […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Alessandro Spadoni, Chiara Daraio, , , | Summary: Acoustic lenses are employed in a variety of applications, from biomedical imaging and surgery, to defense systems, but their performance is limited by their linear operational envelope and complexity. Here we show a dramatic focusing effect and the generation […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Andrei Faraon, Arka Majumdar, Jelena Vuckovic, , | Summary: The generation of non-classical states of light via photon blockade with time-modulated input is analyzed. We show that improved single photon statistics can be obtained by adequately choosing the parameters of the driving laser pulses. An alternative method, […]
Kavli Affiliate: Ralf Heilmann | First 5 Authors: Herman L. Marshall, Ralf Heilmann, Norbert Schulz, Kendrah Murphy, | Summary: We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: The J-Parc Ucn Taskforce, :, Tomokazu Aso, Masatoshi Futakawa, Tomiyoshi Haruyama | Summary: Discussions in the taskforce meetings in the period of Jan.-Mar. 2009 on the technical possibility of the ultracold neutron (UCN) source at the Japan Proton Accelerator Research Complex (J-PARC) is summarized. | Search Query: […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Robert M. Wald, , , , | Summary: The motion of sufficiently small body in general relativity should be accurately described by a geodesic. However, there should be “gravitational self-force” corrections to geodesic motion, analogous to the “radiation reaction forces” that occur in electrodynamics. It is […]
Kavli Affiliate: Carlos Wagner | First 5 Authors: Patrick Draper, Tao Liu, Carlos E. M. Wagner, , | Summary: We analyze the Tevatron reach for neutral Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM), using current exclusion limits on the Standard Model Higgs. We study four common benchmark scenarios for the soft supersymmetry-breaking parameters […]
Kavli Affiliate: Jos Zwanikken | First 5 Authors: Jos Zwanikken, René van Roij, , , | Summary: Within a modified Poisson-Boltzmann theory we study the effect of Bjerrum pairs on the typical length scale $1/bar{kappa}$ over which electric fields are screened in electrolyte solutions, taking into account a simple association-dissociation equilibrium between free ions and […]
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 […]
