Figure 2: Staggered honeycomb lattice. Problem 4. (4 pts) Write down the tight-binding Hamiltonian for a staggered honeycomb lattice. What are the symmetries of the lattice, and what is the minimal number of atoms per unit cell needed? Plot the band structure of this model, either numerically or otherwise.
