Abstract: The semiclassical approximation for electron wave packets in crystals leads to equations that can be derived from a Lagrangian or, under suitable regularity conditions, in a Hamiltonian framework. We use the method of coadjoint orbits applied to the “enlarged” Galilei group to study these issues in the plane.

Keywords: wave packet, semiclassical dynamics, Berry phase, Hamiltonian mechanics.
