Description:
Author(s): Stefanos Kourtis, Titus Neupert, Claudio Chamon, and Christopher Mudry We study two models for spinless fermions featuring topologically nontrivial bands characterized by Chern numbers C=±1 at fractional filling. Using exact diagonalization, we show that, even for infinitely strong nearest-neighbor repulsion, the ground states of these models belong to the recently dis... [Phys. Rev.
