We solve the Dirac equation for a probe fermion…
WitrynaA Brillouin zone is a particular choice of the unit cell of the reciprocal lattice. It is defined as the Wigner-Seitz cell (also called Dirichlet or Voronoi domain of influence) of the reciprocal lattice. It is constructed as the set of points enclosed by the Bragg planes, the planes perpendicular to a connection line from the origin to each ...

Again, what can be qualitatively deducted here? The group velocity is d\omega (k)/dk. This means that, if you form a wave packet that has a central frequency k_0, its maximum will move with the velocity d\omega (k_0)/dk. As the derivative vanishes at the borders, the maximum will not move. cub scouts troops near meWitrynaBrillouin zone.
