Learning to correct spectral methods for simulating turbulent flows

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Gideon Dresdner, Dmitrii Kochkov, Peter Norgaard, Leonardo Zepeda-Núñez, Jamie A. Smith | Summary: Despite their ubiquity throughout science and engineering, only a handful of partial differential equations (PDEs) have analytical, or closed-form solutions. This motivates a vast amount of classical work on numerical simulation of PDEs […]

High-field charge transport and noise in p-Si from first principles

Kavli Affiliate: Austin Minnich | First 5 Authors: David Catherall, Austin Minnich, , , | Summary: The parameter-free computation of charge transport properties of semiconductors is now routine owing to advances in the ab-initio description of the electron-phonon interaction. Many studies focus on the low-field regime in which the carrier temperature equals the lattice temperature […]
