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

Posted by UCSB

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 Chicago

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 […]
