Summary

Description
English: The transverse group velocity (anomalous velocity) for a square lattice of px-ipy (L=-h_bar) orbitals.

The color represents the phase of the wave function. The phase circle around each atom due to the local angular momentum but it also overall flows to the right with a high speed (phase velocity).

The dark region indicated by the white arrow is a node of the envelope function, flowing along the transverse direction. Its motion marks the anomalous velocity. Note that the anomalous velocity is much smaller than the ordinary longitudinal velocity or the phase velocity.
