Possible spin-liquid states on the triangular and kagomé lattices
The frustrated quantum spin-one-half Heisenberg model on the triangular and kagom\'e lattices is mapped onto a single species of fermion carrying statistical flux \ensuremath{\theta}=\ensuremath{\pi}. The corresponding Chern-Simons gauge theory is analyzed at the Gaussian level and found to be massive. This provides a new motivation for the spin-liquid Kalmeyer-Laughlin wave …
