Polymers and Topological Field Theory: A 2 Loop Computation | | Igor Pesando
; | | Date: |
8 Jul 1992 | | Journal: | Phys. Lett. B296 (1992) 341-352 | | Subject: | hep-th | | Abstract: | Within the Quantum Action Principle framework we show the perturbative renormalizability of previously proposed topological lagrangian à la Witten-Fujikawa describing polymers, then we perform a 2 loop computation. The theory turns out to have the same predictive power of De Gennes theory, even though its running coupling constants exhibit a very peculiar behaviour. Moreover we argue that the theory presents two phases , a topological and a non topological one. | | Source: | arXiv, hep-th/9207021 | | Services: | Forum | Review | PDF | Favorites | |
