Amorphous materials have found application in all manner of consumer products and continue to show promise for next generation technologies. Yet thermal transport in this class of materials remains a point of dispute. We studied the mechanisms of thermal transport in amorphous silicon using molecular dynamics simulation and wavelet transform techniques. Perturbation of a single atom in the equi...

The Ludwig-Soret effect, the migration of a species due to a temperature gradient, has been extensively studied without a complete picture of its cause emerging. Here we investigate the dynamics of DNA and spherical particles subjected to a thermal gradient using a combination of Brownian dynamics and the lattice Boltzmann method. We observe that the DNA molecules will migrate to colder regions...
