Spglib

Spglib is a library for finding and handling crystal symmetries written in C. There are the python, fortran, rust, and ruby interfaces.

The detailed algorithm of spglib is described the following text:

• “\(\texttt{Spglib}\): a software library for crystal symmetry search”, Atsushi Togo and Isao Tanaka, https://arxiv.org/abs/1808.01590 (written at version 1.10.4)

Requirements

• C standard: As of version 2.1.0, Spglib explicitly enforces a minimum standard of C11

Features

• Find symmetry operations

• Identify space-group type

• Wyckoff position assignment

• Refine crystal structure

• Find a primitive cell

• Search irreducible k-points
