FINITE-TEMPERATURE MAGNETISM IN THE HUBBARD-MODEL
A novel and physically transparent approach to the finite-temperature Hubbard model at half filling is proposed. It recovers not only the correct dimensionality dependence of antiferromagnetism but, in d=3, interpolates properly between weak and strong coupling interaction strengths for the Néel tem...
