The spatially anisotropic triangular lattice antiferromagnet: Popov-Fedotov method

We present an analysis of the antiferromagnetic Heisenberg model on an triangular lattice with spatially anisotropic J1-J2 exchange interactions. We apply the Popov-Fedotov method based on introducing an imaginary valued chemical potential to enforce the auxiliary fermion constraint exactly. The sta...
