  • Description: The interplay between the spin-orbit coupling and a lattice modulation in the Lieb lattice is studied. The electron structure of the tight-binding model on the Lieb lattice features both the flat and the Dirac linearly dispersing bands. Within the Lieb lattice the spinorbit coupling can induce a topological insulating state, while the lattice modulation breaks the topology. As a result of the interplay, a topological competition between the spin-orbit coupling and the lattice modulation occurs. The topology of the system is detected by the edge modes in open boundaries.
