Quasi-ballistic phonon transport effects on the determination of the mean-free path accumulation function for the effective thermal conductivity

Posted by February 20, 2015UCSB

Kavli Affiliate: John E. Bowers | First 5 Authors: Ashok T. Ramu, John E. Bowers, , , | Summary: The mean-free path (MFP) accumulation function for the effective thermal conductivity, introduced by Dames and Chen is a compact, universal and highly useful summary of the effect of ballistic thermal transport on the effective thermal conductivity […]

Nonlinear stochastic growth rates and redshift space distortions

Posted by February 6, 2015Chicago

Kavli Affiliate: Elise Jennings | First 5 Authors: Elise Jennings, David Jennings, , , | Summary: The linear growth rate is commonly defined through a simple deterministic relation between the velocity divergence and the matter overdensity in the linear regime. We introduce a formalism that extends this to a nonlinear, stochastic relation between $θ= nabla […]

Cool Core Bias in Sunyaev-Zel’dovich Galaxy Cluster Surveys

Posted by January 19, 2015Chicago

Kavli Affiliate: Bradford Benson | First 5 Authors: Henry W. Lin, Michael McDonald, Bradford Benson, Eric Miller, | Summary: Sunyaev-Zeldovich (SZ) surveys find massive clusters of galaxies by measuring the inverse Compton scattering of cosmic microwave background off of intra-cluster gas. The cluster selection function from such surveys is expected to be nearly independent of […]

Subwavelength edge detection through trapped resonances in waveguides

Posted by January 10, 2015Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Miguel Molerón, Chiara Daraio, , , | Summary: Lenses that can collect the perfect image of an object must restore propagative and evanescent waves. However, for efficient information transfer, e.g., in compressed sensing, it is often desirable to detect only the fast spatial variations of the wave […]

Multiple Soft Limits of Cosmological Correlation Functions

Posted by September 22, 2014Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Austin Joyce, Justin Khoury, Marko Simonović, , | Summary: We derive novel identities satisfied by inflationary correlation functions in the limit where two external momenta are taken to be small. We derive these statements in two ways: using background-wave arguments and as Ward identities following from the […]

Large-area Reflective Infrared Filters for Millimeter/sub-mm Telescopes

Posted by July 22, 2014Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Z. Ahmed, J. A. Grayson, K. L. Thompson, C. L. Kuo, G. Brooks | Summary: Ground-based millimeter and sub-millimeter telescopes are attempting to image the sky with ever-larger cryogenically-cooled bolometer arrays, but face challenges in mitigating the infrared loading accompanying large apertures. Absorptive infrared filters supported by […]

Network of Time-Multiplexed Optical Parametric Oscillators as a Coherent Ising Machine

Posted by July 10, 2014Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Alireza Marandi, Zhe Wang, Kenta Takata, Robert L. Byer, Yoshihisa Yamamoto | Summary: Finding the ground states of the Ising Hamiltonian [1] maps to various combinatorial optimization problems in biology, medicine, wireless communications, artificial intelligence, and social network. So far no efficient classical and quantum algorithm is […]

Solar System objects as cosmic rays detectors

Posted by May 22, 2014Chicago

Kavli Affiliate: Paolo Privitera | First 5 Authors: Paolo Privitera, Pavel Motloch, , , | Summary: In a recent Letter (Rimmer et al. 2014), Jupiter is presented as an efficient detector for Ultra-High Energy Cosmic Rays (UHECRs), through measurement by an Earth-orbiting satellite of gamma rays from UHECRs showers produced in Jupiter’s atmosphere. We show […]

Delensing Galaxy Surveys

Posted by May 6, 2014Chicago

Kavli Affiliate: Chihway Chang | First 5 Authors: Chihway Chang, Bhuvnesh Jain, , , | Summary: Weak gravitational lensing can cause displacements, magnification, rotation and shearing of the images of distant galaxies. Most studies focus on the shear and magnification effects since they are more easily observed. In this paper we focus on the effect […]

Statistics of Dark Matter Substructure: II. Comparison of Model with Simulation Results

Posted by March 26, 2014Peking

Frank C. van den Bosch, Fangzhou Jiang, , , | Summary: [[{“value”:”We compare subhalo mass and velocity functions obtained from different simulations with different subhalo finders among each other, and with predictions from the new semi-analytical model of Jiang & van den Bosch (2014). We find that subhalo mass functions (SHMFs) obtained using different subhalo […]
