Time-reversal symmetry breaking Abelian chiral spin liquid in Mott phases of three-component fermions on the triangular lattice

This paper shows that the standard Hubbard model on the triangular lattice with three color fermions has a chiral phase at intermediate coupling when kinetic fluctuations are strong enough to destroy the three-sublattice long range order but not strong enough yet to drive the system into another phase or into the metallic regime.
