In this note we consider boundary perturbations in the A-Series unitary minimal models by r,r+2 fields on superpositions of boundaries. In particular, we consider perturbations by boundary condition changing operators. Within conformal perturbation theory we explicitly map out the space of perturbative renormalisation group flows for the example 13 and find that this sheds light on more general r,r+2 perturbations. Finally, inspired by a lattice realisation we find a simple diagrammatic…

Conformal perturbation theory beyond the leading order

Higher-order conformal perturbation theory is studied for theories with and without boundaries. We identify systematically the universal quantities in the beta function equations, and we give

Bulk flows in Virasoro minimal models with boundaries

The behaviour of boundary conditions under relevant bulk perturbations is studied for the Virasoro minimal models. In particular, we consider the bulk deformation by the least relevant bulk field

Higher order conformal perturbation theory

We consider a string stretched between two diagonal branes on a bosonic torus under a perturbation of one of the radii. In the world‐sheet description, this corresponds to a perturbation of a

Defect flows in minimal models

In this paper we study a simple example of a two-parameter space of renormalisation group flows of defects in Virasoro minimal models. We use a combination of exact results, perturbation theory and

In the context of two-dimensional rational conformal field theories we consider topological junctions of topological defect lines with boundary conditions. We refer to such junctions as open

Perturbative and non-perturbative studies in low dimensional quantum field theory

A relevant perturbation of a conformal field theory (CFT) on the half-plane, by both a bulk and boundary operator, often leads to a massive theory with a particle description in terms of the bulk

Perturbed conformal field theories with boundary

This thesis is concerned with renormalisation group flows in two-dimensional conformal field theories with boundary. In two dimensions, the local conformal symmetry algebra, consisting of local

Landau-Ginzburg description of boundary critical phenomena in two dimensions

The Virasoro minimal models with boundary are described in the Landau-Ginzburg theory by introducing a boundary potential, function of the boundary field value. The ground state field configurations



Renormalisation group flows of boundary theories

We review recent developments in the theory of renormalisation group flows in minimal models with boundaries. Among these, we discuss in particular the perturbative calculations of Recknagel et al,

Integrable and Conformal Boundary Conditions for ŝ l ( 2 ) A – D – E Lattice Models and Unitary Minimal Conformal Field Theories

Integrable boundary conditions are studied for critical A–D–E and general graph-based lattice models of statistical mechanics. In particular, using techniques associated with the Temperley-Lieb

Renormalization Group and Perturbation Theory Near Fixed Points in Two-Dimensional Field Theory

The behavior of the renormalization group is investigated in the neighborhood of the fixed points described by the ''minimal'' conformal theories M/sub p/ with p>>1. In the leading approximation in

Boundary structure constants for the A-series Virasoro minimal models

Exact conformal-field-theory results on the multichannel Kondo effect: Single-fermion Green's function, self-energy, and resistivity.

A conformal-field-theory approach has recently been developed for quantum-impurity problems including the overscreened'' multichannel Kondo model and perturbative proof of the [ital g] theorem'' governing the change in residual entropy under a renormalization-group flow between two boundary fixed points is given.

Scaling and Renormalization in Statistical Physics

This text provides a thoroughly modern graduate-level introduction to the theory of critical behaviour. Beginning with a brief review of phase transitions in simple systems and of mean field theory,

Edge critical behaviour of the two-dimensional tri-critical Ising model

Using previous results from boundary conformal field theory and integrability, a phase diagram is derived for the two-dimensional Ising model at its bulk tri-critical point as a function of boundary
