TL;DR: The axion field in a crystal is given by the non-Abelian Chern-Simons integral, which depends on the Berry connection matrix of the band structure.

Boltzmann transport calculation of collinear spin transport on short timescales
TL;DR: In this article, the shape of the resulting spin current/density depends critically on the interplay between transport and scattering, and on the energetic distribution of the injected hot electrons, which has a decisive effect on the spin dynamics.

Modification of spintronic terahertz emitter performance through defect engineering
Dennis M. Nenno,Laura Scheuer,Dominik Sokoluk,Sascha Keller,Garik Torosyan,Alexander Brodyanski,Jörg Lösch,Marco Battiato,Marco Rahm,Rolf Binder,Hans Christian Schneider,Rene Beigang,Evangelos Th. Papaioannou +12 more
TL;DR: In this paper, the influence of the electron-defect scattering lifetime on the spectral shape and the interface transmission on the THz amplitude was investigated, and how this is linked to structural defects of bilayer emitters.
Anisotropic phonon-mediated electronic transport in chiral Weyl semimetals
Christina A. C. Garcia,Dennis M. Nenno,Dennis M. Nenno,Georgios Varnavides,Georgios Varnavides,Prineha Narang +5 more
TL;DR: In this article, a first-principles theoretical study of chiral Weyl semimetals with strong and anisotropic electron-phonon coupling is presented, and the emergence of hydrodynamics in these systems is predicted.

TL;DR: In this article, an ab initio theoretical study of the electronic transport and electron-phonon scattering in six group V transition metal ditetrelides, that is, XY$_2$ (X = V, Nb, Ta and Y = Si, Ge), host composite Weyl nodes on high symmetry lines, with Kramers-Weyl fermions at time-reversal invariant momenta.
