Polymers and Topological Field Theory : a 2 Loop Computation
نویسنده
چکیده
Within the Quantum Action Principle framework we show the perturbative renormalizability of previously proposed topological lagrangianà la Witten-Fujikawa describing polymers, then we perform a 2 loop computation. The theory turns out to have the same pre-dictive 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.

Notes on Topological Field Theory
Introduction The notes give a survey of the basics of the following topological field theories: • The Chern-Simons gauge theory on 3-manifolds, its renormalization, geometric quantization, computation of partition functions by surgery, and relation with Jones Polynomials • Twisted N = 2 supersymmetric Yang-Mills theory on 4-manifolds, its reduction to N = 1 theory with a mass gap, and computati...
متن کاملLattice Perturbation Theory by Computer Algebra : A Three - Loop Result for the Topological Susceptibility
We present a scheme for the analytic computation of renormalization functions on the lattice, using a symbolic manipulation computer language. Our first nontrivial application is a new three-loop result for the topological susceptibility.
متن کاملM-Theory and Topological Strings–I
The RF 2g−2 terms of Type IIA strings on Calabi-Yau 3-folds, which are given by the corresponding topological string amplitudes (a worldsheet instanton sum for all genera), are shown to have a simple M-theory interpretation. In particular, a Schwinger one-loop computation in M-theory with wrapped M2 branes and Kaluza-Klein modes going around the loop reproduces the all genus string contribution...
متن کاملPolynomial Invariants for Su ( 2 ) Monopoles
We present an explicit expression for the topological invariants associated to SU(2) monopoles in the fundamental representation on spin four-manifolds. The computation of these invariants is based on the analysis of their corresponding topological quantum field theory, and it turns out that they can be expressed in terms of Seiberg-Witten invariants. In this analysis we use recent exact result...
متن کاملLoop Equations and the Topological Phase of Multi - Cut Matrix Models
We study the double scaling limit of mKdV type, realized in the two-cut Hermitian matrix model. Building on the work of Periwal and Shevitz and of Nappi, we find an exact solution including all odd scaling operators, in terms of a hierarchy of flows of 2× 2 matrices. We derive from it loop equations which can be expressed as Virasoro constraints on the partition function. We discover a “pure to...
