Orbital Character / Texture

Current status: READY

The implemented quantity is k/band-resolved projector weight,

$$w_{\alpha n\mathbf k} = |\langle\phi_\alpha|\psi_{n\mathbf k}\rangle|^2.$$

Analyze renders the result as a fat-band-style plot.

caution

This is orbital character. It is not automatically an orbital-angular-momentum expectation value $\langle L_x,L_y,L_z\rangle$.
