Crystal momentum

A wave packet with dispersion, which causes the group velocity and phase velocity to be different. This image is a 1-dimensional real wave, but electron wave packets are 3-dimensional complex waves.

In solid-state physics crystal momentum or quasimomentum is a momentum-like vector associated with electrons in a crystal lattice. It is defined by the associated wave vectors $\mathbf{k}$ of this lattice, according to

(where $\hbar$ is the reduced Planck's constant). Like mechanical momentum, crystal momentum is frequently conserved, making it useful to physicists and materials scientists as an analytical tool.
