5 Feb 2001 | | Journal: | Phys Rev Lett, 86 (6), 958-61 | | Abstract: | The phase transition of the Gross-Neveu model with N fermions is investigated by means of a nonperturbative 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 explicitly verified that the Neveu-Yukawa model belongs to the same universality class as the Gross-Neveu model. | | Source: | PubMed, pmid11177984 | | Services: | Forum | Review | Favorites | |
