vibeqc.aiccm2026dev_b_band_structure

vibeqc.aiccm2026dev_b_band_structure(result, system, kpath, *, spin='total', n_electrons_per_cell=None)

Sample the converged finite-torus Fock matrix along a k-path.

The returned bands are exact at the cyclic cluster’s folded character points. Between them the path is the finite-torus interpolation defined by the reconstructed real-space Fock blocks, so it should be converged with respect to lattice_extension before quantitative interpretation.

Parameters:

• result (object)

• system (vibeqc._vibeqc_core.PeriodicSystem)

• kpath (KPath)

• spin (str)

• n_electrons_per_cell (int | None)

Return type:

BandStructure
