Codes for the project Crystallography, Group Cohomology, and Lieb–Schultz–Mattis Constraints
Content
This repository contains the following three parts
GAP codes
Read both SpaceGroupCohomologyData.gi and SpaceGroupCohomologyFunctions.gi Main command that outputs the mod-2 cohomology and LSM anomaly classes: SpaceGroupCohomologyRingGapInterface(IT); where IT is the numbering of the space group (1<=IT<=230).
Mathematica codes
SpaceGroupCohomology_Data.nb contains the standard inhomogeneous functions for the 1-,2-, and 3-cocycles (except for No. 225, 227, and 229) Execute the "Preparations" section first.
Sage codes
Codes to obtain the explicit cochain representatives for degree-3 generators of several complicated space groups
