Impact of pickup ions on the shock front nonstationarity and energy dissipation of the heliospheric termination shock: Two-dimensional full particle simulations and comparison with Voyager 2 observations

Posted by klaurent MIT

Kavli Affiliate: John D. Richardson | First 5 Authors: Zhongwei Yang, Ying D. Liu, John D Richardson, Quanming Lu, Can Huang | Summary: The transition between the supersonic solar wind and the subsonic heliosheath, the termination shock (TS), was observed by Voyager 2 (V2) on 2007 August 31-September 1 at a distance of 84 AU […]

Frequency fluctuations in silicon nanoresonators

Posted by klaurent Caltech

Kavli Affiliate: Michael L. Roukes | First 5 Authors: Marc Sansa, Eric Sage, Elizabeth C. Bullard, Marc Gély, Thomas Alava | Summary: Frequency stability is key to performance of nanoresonators. This stability is thought to reach a limit with the resonator’s ability to resolve thermally-induced vibrations. Although measurements and predictions of resonator stability usually disregard […]

Statistical Measures of Planck Scale Signal Correlations in Interferometers

Posted by klaurent Chicago

Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, Ohkyung Kwon, , , | Summary: A model-independent statistical framework is presented to interpret data from systems where the mean time derivative of positional cross correlation between world lines, a measure of spreading in a quantum geometrical wave function, is measured with a […]

Thermal Maps of Gases in Heterogeneous Reactions

Posted by klaurent Berkeley

Kavli Affiliate: Omar M. Yaghi | First 5 Authors: Nanette N. Jarenwattananon, Stefan Gloeggler, Trenton Otto, Arek Melkonian, William Morris | Summary: Over 85% of all chemical industry products are made using catalysts, with the overwhelming majority of these employing heterogeneous catalysts functioning at the gas-solid interface. Consequently, optimizing catalytic reactor design attracts much effort. […]

Physics Case for the International Linear Collider

Posted by klaurent Tokyo

Kavli Affiliate: Mihoko Nojiri | First 5 Authors: Keisuke Fujii, Christophe Grojean, Michael E. Peskin, Tim Barklow, Yuanning Gao | Summary: We summarize the physics case for the International Linear Collider (ILC). We review the key motivations for the ILC presented in the literature, updating the projected measurement uncertainties for the ILC experiments in accord […]

Dispersion Distance and the Matter Distribution of the Universe in Dispersion Space

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Kiyoshi Wesley Masui, Kris Sigurdson, , , | Summary: We propose that "standard pings", brief broadband radio impulses, can be used to study the three-dimensional clustering of matter in the Universe even in the absence of redshift information. The dispersion of radio waves as they travel […]

Influences of quantum mechanically mixed electronic and vibrational pigment states in 2D electronic spectra of photosynthetic systems: Strong electronic coupling cases

Posted by klaurent Berkeley

Kavli Affiliate: Graham R. Fleming | First 5 Authors: Yuta Fujihashi, Graham R. Fleming, Akihito Ishizaki, , | Summary: In 2D electronic spectroscopy studies, long-lived quantum beats have recently been observed in photosynthetic systems, and it has been suggested that the beats are produced by quantum mechanically mixed electronic and vibrational states. Concerning the electronic-vibrational […]
