Description:
Author(s): Pramod Kumar, Tuomas I. Vanhala, and Päivi Törmä The properties of a phase at finite interactions can be significantly influenced by the underlying dispersion of the noninteracting Hamiltonian. We demonstrate this by studying the repulsive Hubbard model on the two-dimensional Lieb lattice, which has a flat band for vanishing interaction U . We perf... [Phys. Rev.
