RG Flows in the D-Series of Minimal CFTs
Using results of the thermodynamic Bethe Ansatz approach and conformal perturbation theory we argue that the φ1,3-perturbation of a unitary minimal (1 + 1)-dimensional conformal field theory (CFT) in the D-series of modular invariant partition functions induces a renormalization group (RG) flow to the next-lower model in the D-series. An exception is the first model in the series, the 3-state P...
متن کاملBoundary RG Flows of N = 2 Minimal Models
We study boundary renormalization group flows of N = 2 minimal models using Landau-Ginzburg description of B-type. A simple algebraic relation of matrices is relevant. We determine the pattern of the flows and identify the operators that generate them. As an application, we show that the charge lattice of B-branes in the level k minimal model is Zk+2. We also reproduce the fact that the charge ...
متن کاملThe dilute A L models and the Φ 1 , 2 perturbation of unitary minimal CFTs
Motivated by recent studies by Dorey, Pocklington and Tateo[24, 25]for unitary minimal models perturbed by φ1,2, we examine the thermodynamics of one dimensional quantum systems, whose counterparts in the 2D classical model are the dilute AL models in regime 2. The functional relations for arbitrary values of L are established. Guided by numerical evidences, we obtain a set of coupled integral ...
متن کاملThe dilute A L models and the integrable perturbations of unitary minimal CFTs
The dilute A L models and the integrable perturbations of unitary minimal CFTs. Abstract Recently, a set of thermodynamic Bethe ansatz equations is proposed by Dorey, Pocklington and Tateo for unitary minimal models perturbed by φ 1,2 or φ 2,1 operator. We examine their results in view of the lattice analogues, dilute A L models at regime 1 and 2. Taking M 5,6 + φ 1,2 and M 3,4 + φ 2,1 as the s...
متن کاملCounting RG flows
Interpreting renormalization group flows as solitons interpolating between different fixed points, we ask various questions that are normally asked in soliton physics but not in renormalization theory. Can one count RG flows? Are there different “topological sectors” for RG flows? What is the moduli space of an RG flow, and how does it compare to familiar moduli spaces of (supersymmetric) dowai...
