Topology of Disconnected Elementary Band Representations
Jennifer Cano, Barry Bradlyn, Zhijun Wang +5
Elementary band representations are the fundamental building blocks of atomic limit band structures. They have the defining property that at partial filling they cannot be both gap…
Building Blocks of Topological Quantum Chemistry: Elementary Band Representations
Jennifer Cano, Barry Bradlyn, Zhijun Wang +5
The link between chemical orbitals described by local degrees of freedom and band theory, which is defined in momentum space, was proposed by Zak several decades ago for spinless s…
Graph Theory Data for Topological Quantum Chemistry
M. G. Vergniory, L. Elcoro, Zhijun Wang +5
Topological phases of noninteracting particles are distinguished by global properties of their band structure and eigenfunctions in momentum space. On the other hand, group theory…
Double crystallographic groups and their representations on the Bilbao Crystallographic Server
Luis Elcoro, Barry Bradlyn, Zhijun Wang +7
A new section of databases and programs devoted to double crystallographic groups (point and space groups) has been implemented in the Bilbao Crystallographic Server (http://www.cr…
