12 Jul 2000 | | Journal: | Phys.Rev.Lett. 86 (2001) 958-961 | | Subject: | hep-th hep-ph | | Abstract: | The phase transition of the Gross-Neveu model with N fermions is investigated by means of a non-perturbative evolution equation for the scale dependence of the effective average action. The critical exponents and scaling amplitudes are calculated for various values of N in d=3. It is also explicitely verified that the Neveu-Yukawa model belongs to the same universality class as the Gross-Neveu model. | | Source: | arXiv, hep-th/0007093 | | Services: | Forum | Review | PDF | Favorites | |
