Journal ArticleDOI
Topological quantum chemistry
Barry Bradlyn,Luis Elcoro,Jennifer Cano,Maia G. Vergniory,Maia G. Vergniory,Maia G. Vergniory,Zhijun Wang,Claudia Felser,Mois I. Aroyo,B. Andrei Bernevig +9 more
TL;DR: A complete electronic band theory is proposed, which builds on the conventional band theory of electrons, highlighting the link between the topology and local chemical bonding and can be used to predict many more topological insulators.
Journal ArticleDOI
Beyond Dirac and Weyl fermions: Unconventional quasiparticles in conventional crystals
Barry Bradlyn,Jennifer Cano,Zhijun Wang,Maia G. Vergniory,Claudia Felser,R. J. Cava,B. Andrei Bernevig +6 more
TL;DR: The guiding principle of the classification is to find irreducible representations of the little group of lattice symmetries at high-symmetry points in the Brillouin zone for each of the 230 space groups (SGs), the dimension of which corresponds to the number of bands that meet at the high-Symmetry point.
Journal ArticleDOI
Kubo formulas for viscosity: Hall viscosity, Ward identities, and the relation with conductivity
TL;DR: In this article, the authors derived from first principles the Kubo formula for the stress-stress response function at zero wave vector that can be used to define the full complex frequency-dependent viscosity tensor, both with and without a uniform magnetic field.
Journal ArticleDOI
Building blocks of topological quantum chemistry: Elementary band representations
Jennifer Cano,Barry Bradlyn,Zhijun Wang,Luis Elcoro,Maia G. Vergniory,Maia G. Vergniory,Maia G. Vergniory,Claudia Felser,Mois I. Aroyo,B. Andrei Bernevig +9 more
TL;DR: In this paper, it was shown that the Wyckoff positions can be used to generate disconnected elementary band representations for spin-orbit coupled systems with time-reversal symmetry.
Journal ArticleDOI
Chiral topological semimetal with multifold band crossings and long Fermi arcs

TL;DR: AlPt is shown to be a chiral topological material with four-fold and six-fold degeneracies in the band structure as discussed by the authors, which can be viewed as a higher spin generalization of Weyl fermions.
