pythtb.WFArray.psi_nk

property WFArray.psi_nk

The Bloch wavefunctions.

These are the \(|\psi_{n\mathbf{k}}\rangle\) states including the plane-wave phase factors.

Returns:

np.ndarray

The Bloch wavefunctions. Shape is (*shape_mesh, nstates, norb[, nspin]).

Raises:

ValueError

If the wavefunctions are not initialized or if k-axes are not present in the mesh
