Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, , , , | Summary: A model quantum system is proposed to describe position states of a massive body in flat space on large scales, excluding all standard quantum and gravitational degrees of freedom. The model is based on standard quantum spin commutators, […]
Kavli Affiliate: Mark Bowick | First 5 Authors: Zhenwei Yao, Mark Bowick, Xu Ma, Rastko Sknepnek, | Summary: If an inextensible thin sheet is adhered to a substrate with a negative Gaussian curvature it will experience stress due to geometric frustration. We analyze the consequences of such geometric frustration using analytic arguments and numerical simulations. […]
Kavli Affiliate: Robert A. Cameron | First 5 Authors: Markos Trichas, Paul J. Green, John D. Silverman, Tom Aldcroft, Wayne Barkhouse | Summary: From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic follow up using the FLWO, […]
Kavli Affiliate: Sarah Church | First 5 Authors: Matthew Sieth, Sarah Church, Judy M. Lau, Patricia Voll, Todd Gaier | Summary: We report on the development of W-band (75-110 GHz) heterodyne receiver technology for large-format astronomical arrays. The receiver system is designed to be both mass-producible, so that the designs could be scaled to thousands […]
Kavli Affiliate: Keith Schwab | First 5 Authors: Kin Chung Fong, Keith Schwab, , , | Summary: Graphene is a material with remarkable electronic properties and exceptional thermal transport properties near room temperature, which have been well examined and understood. However at very low temperatures the thermodynamic and thermal transport properties are much less well […]

Kavli Affiliate: Geza Gyuk | First 5 Authors: Michael Solontoi, Mark Hammergren, Geza Gyuk, Andrew Puckett, | Summary: We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takashi Uchiyama, Shinji Miyoki, Souichi Telada, Kazuhiro Yamamoto, Masatake Ohashi | Summary: The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror’s thermal fluctuation in a GW detector […]
Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Juan M. R. Parrondo, Stephan W. Gril, , | Summary: Both genomic stability and sustenance of day-to-day life rely on efficient and accurate readout of the genetic code. Single-molecule experiments show that transcription and replication are highly stochastic and irregular processes, with the polymerases frequently […]
Kavli Affiliate: Lena Fitting Kourkoutis | First 5 Authors: Huolin L. Xin, Julia A. Mundy, Zhongyi Liu, Randi Cabezas, Robert Hovden | Summary: The thousandfold increase in data-collection speed enabled by aberration-corrected optics allows us to overcome an electron microscopy paradox – how to obtain atomic-resolution chemical structure in individual nanoparticles, yet record a statistically […]
