Temperature dependence of antiferromagnetic order in the Hubbard model
T. Baier, E. Bick, C. Wetterich
We suggest a method for an approximative solution of the two dimensional Hubbard model close to half filling. It is based on partial bosonisation, supplemented by an investigation…

Antiferromagnetic gap in the Hubbard model
T. Baier, E. Bick, C. Wetterich
We compute the temperature dependence of the antiferromagnetic order parameter and the gap in the two dimensional Hubbard model at and close to half filling. Our approach is based…
