The sublattice symmetry ensures that the HamiltonianHobeysPHP=−H[42,43], with the operator Pacting ascα 1 −→Pcα 1andc α 2 −→−Pc 2. This is a very natural condition when the Hamiltonian contains only hoppings from sublattice 1 to sublattice 2.

WebThe sublattice symmetry reads σ z H 0 ( k) σ z = − H 0 ( k). Sublattice symmetry is only approximate, and it is consequence of the nearest neighbor tight-binding model. Just like the inversion symmetry mentioned in the video, it protects the Dirac points and needs to be broken in order to open a gap. Weband Xlabel sublattices A and B, and p represents the crystal momentum in the lattice’s Brillouin zone. It is convenient—and common in the graphene literature—to regard the sublattice degree of freedom as a pseudospin, with the A sublattice being the R〉pseudospin state and the B sublattice being the ↓〉 pseudospin state.
