Webatic and formally rigorous approach based on the Kubo-Streda formula. The various different contributions that have been identified in the semiclassical approach, can, for the particular case of two-dimensional Dirac bands, all be di-rectly linked to particular Feynman-diagram subsums in the Kubo-Streda formalism. The correspondence is summarized http://www-m7.ma.tum.de/foswiki/pub/M7/Analysis/RanOp14/ChapterKubo.pdf

WebWe have studied the longitudinal thermal conductivity of the surface of a three-dimensional time-reversal symmetric topological superconductor with random disorder. Majorana … Web23 Jun 2024 · To help clarify this issue, we also derive the slightly generalized Kubo–Streda formula in the level of the effective quantum theory. In this level, it is this generalized Kubo–Streda formula rather than the usual one [10, 11] that leads to the same physical picture as the pre- sent SB theory. indiana church of christ
