|Title:||Phonon hall thermal conductivity from the Green-Kubo formula||Authors:||Wang, J.-S.
|Issue Date:||6-Aug-2009||Citation:||Wang, J.-S., Zhang, L. (2009-08-06). Phonon hall thermal conductivity from the Green-Kubo formula. Physical Review B - Condensed Matter and Materials Physics 80 (1) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevB.80.012301||Abstract:||We derive an exact formula for the thermal-conductivity tensor of a ballistic phonon Hall model. It is found that, although the diagonal elements of the conductivity tensor diverge to infinite, the off-diagonal elements are finite, antisymmetric, and odd in magnetic field. The off-diagonal elements are nonzero only if the dynamic matrix of the phonon system breaks mirror-reflection symmetry. The results are obtained without perturbative treatment of the spin-phonon interactions. © 2009 The American Physical Society.||Source Title:||Physical Review B - Condensed Matter and Materials Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/97527||ISSN:||10980121||DOI:||10.1103/PhysRevB.80.012301|
