Description:
Author(s): Murad Tovmasyan, Evert P. L. van Nieuwenburg, and Sebastian D. Huber We study a one-dimensional model of interacting bosons on a lattice with two flat bands. Regular condensation is suppressed due to the absence of a well-defined minimum in the single-particle spectrum. We find that interactions stabilize a number of nontrivial phases such as a pair (quasi)condensate... [Phys. Rev. B 88, 220510] Published Thu Dec 26, 2013
