Abstract

The specific heat and the electrical conductivity are calculated in the Hubbard model in Hartree‐Fock approximation (HFA) for an antiferromagnetic ordering and for arbitrary band filling using the antiferromagnetic solutions which are found in HFA and which are established with respect to the existence of double solutions of the NΓ©el temperature in the framework of a theory taking into account fluctuations of the spin.

We investigate a magnetic transition in the half-filled Hubbard model on the triangular lattice. By making use of the path-integral renormalization group (PIRG) method with a spin-rotated frame, we calculate the ground state energy and charge/spin correlation functions for a cluster with 36 sites. W
