Universality of mean-field antiferromagnetic order in an anisotropic 3D Hubbard model at half-filling

E. Langmann, J. Lenells

We study the 3D anisotropic Hubbard model on a cubic lattice with hopping parameter $t$ in the $x$- and $y$-directions and a possibly different hopping parameter $t_z$ in the $z$-d…
