Weak Mott insulators on the triangular lattice: Possibility of a gapless nematic quantum spin liquid
We study the energetics of Gutzwiller projected BCS states of various symmetries for the triangular lattice antiferromagnet with a four-particle ring exchange using variational Monte Carlo methods. In a range of parameters the energetically favored state is found to be a projected dx2−y2 paired stat...
