pythtb.Wannier.tilde_states

property Wannier.tilde_states

WFArray corresponding to the Bloch-like (tilde) states.

These are the Bloch-like states that are Fourier transformed to form the Wannier functions. They are related to the original energy eigenstates via the (semi-) unitary transformation

\[|\tilde{\psi}_{n\mathbf{k}} \rangle = \sum_{m=1}^{N} U_{mn}^{(\mathbf{k})} |\psi_{m\mathbf{k}} \rangle\]
