Phonon thermal hall conductivity from scattering with collective fluctuations

HIGHLIGHTS

• who: Lu00e9o Mangeolle and collaborators from the u00c9coleUniversity of Santa Barbara, California, USA have published the article: Phonon Thermal Hall Conductivity from Scattering with Collective Fluctuations, in the Journal: (JOURNAL) of 21/Dec/2022
• what: The authors discuss how this occurs via many-body scattering of phonons by collective modes: a consequence of nonGaussian correlations of the latter modes. The authors show that the full scattering data needed to understand the thermal conductivity (both longitudinal and Hall components) can be obtained from the time- and space-dependent correlation functions of the Q fields. The authors . . .
