Crystal hamiltonian
Did you know?
In a crystal, we take the single particle hamiltonian to be H= H at+ U; (1) where H at is the hamiltonian for a single atom and U encodes all the di erences between the true potential in the crystal and the potential of an isolated atom. We assume U!0 at the centre of each atom in the crystal. The single particle states in the crystal are then Webset individually, as the operators K^ for each set all commute with the Hamiltonian. 2.2.2 Interacting Bloch particles If an interaction term between different particles is present in the Hamiltonian, the crystal mo-menta of each set of particles will not, in general, be conserved, but the total crystal momentum
WebThe time-reversed Hamiltonian simply reads , since we are dealing with an antiunitary symmetry transformation operator. The explicit action of complex conjugation can be replaced by introducing the respective operation K, thus .
