On Perturbations of Unitary Minimal Models by Boundary Condition Changing Operators
نویسنده
چکیده
In this note we consider boundary perturbations in the A-Series unitary minimal models by φr,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 φ13 and find that this sheds light on more general φr,r+2 perturbations. Finally, we find a simple diagrammatic representation for the space of flows from a single Cardy boundary condition.

On relevant boundary perturbations of unitary minimal models
We consider unitary Virasoro minimal models on the disk with Cardy boundary conditions and discuss deformations by certain relevant boundary operators, analogous to tachyon condensation in string theory. Concentrating on the least relevant boundary field, we can perform a perturbative analysis of renormalization group fixed points. We find that the systems always flow towards stable fixed point...
متن کاملNonlocal operator basis for the path representation of the unitary minimal models
We propose a new operator interpretation for the lattice paths of the unitary minimal models M(k + 1, k + 2). These operators are akin to the modes of a complex fermion, but at the same time, they capture some characteristics of Z k parafermions in that there is a bound on the number of allowed successive operators (which is k − 1). The operators act non-locally on the path: Their action modifi...
متن کاملMinimal model boundary flows and c = 1 CFT
We consider perturbations of unitary minimal models by boundary fields. Initially we consider the models in the limit as c → 1 and find that the relevant boundary fields all have simple interpretations in this limit. This interpretation allows us to conjecture the IR limits of flows in the unitary minimal models generated by the fields φ rr of 'low' weight. We check this conjecture using the tr...
متن کاملReflection factors and exact g-functions for purely elastic scattering theories
We discuss reflection factors for purely elastic scattering theories and relate them to perturbations of specific conformal boundary conditions, using recent results on exact off-critical g-functions. For the non-unitary cases, we support our conjectures using a relationship with quantum group reductions of the sine-Gordon model. Our results imply the existence of a variety of new flows between...
متن کاملBoundary operators and touching of loops in 2 d gravity 1
We investigate the correlators in unitary minimal conformal models coupled to two-dimensional gravity from the two-matrix model. We show that simple fusion rules for all of the scaling operators exist. We demonstrate the role played by the boundary operators and discuss its connection to how loops touch each other.
