Vanhala, Dong-Hee Kim, and Päivi Törmä The ground state and transport properties of the Lieb lattice flat band in the presence of an attractive Hubbard interaction are considered. It is shown that the superfluid weight can be large even for an isolated and strictly flat band. Moreover the superfluid weight is proportional to the interact… [Phys. Rev.
