The above figure shows symmetry analysis for the band structure. The author writes:
The band symmetry and parity analyses were carried out with the QUANTUM ESPRESSO package based on GBRV PBE scalar relativistic potentials and Pseudodojo fully relativistic potentials.
How do this with QE? In particular, how to find the irreducible representations for bands and the point group for high symmetry $K$ points?
