Ultracold atoms carrying orbital angular momentum: Engineering topological phases in lattices

“…In order for the CLSs to span all the sites of the lattice, we remove the A Nc site. Assuming that the interaction strength is much smaller than the energy gap 2 √ 2J 2 between the lowest and zero-energy flat bands, we can project the kinetic and interacting parts of the Hamiltonian to the two lowest degenerate flat bands [43,44]. The total set H of states with the two bosons in the lowest bands can be divided into 4 subspaces according to the values of their self-energy.…”
