Crystallography, group cohomology, and Lieb–Schultz–Mattis constraints

SciPost Physics
We compute the mod-2 cohomology ring for three-dimensional (3D) space groups and establish a connection between them and the lattice structure of crystals with space group symmetry.

From Gauge Anomalies to Gerbes and Gerbal Representations: Group Cocycles in Quantum Theory

Acta Polytechnica, 2010
In this paper I shall discuss the role of group cohomology in quantum mechanics and quantum field theory. First, I recall how cocycles of degree 1 and 2 appear naturally in the context of gauge anomalies.
