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 […]
