Explicit expressions for Virasoro singular vectors
Gérard M T Watts
We present two explicit expressions for generic singular vectors of type of the Virasoro algebra. These results follow from the paper of Bauer et al which presented recursi…
One-point functions in finite volume/temperature: a case study
I. M. Szécsényi, G. Takács, G. M. T. Watts
We consider finite volume (or equivalently, finite temperature) expectation values of local operators in integrable quantum field theories using a combination of numerical and anal…
Excited state g-functions from the Truncated Conformal Space
Gabor Takacs, Gerard Watts
In this paper we consider excited state g-functions, that is, overlaps between boundary states and excited states in boundary conformal field theory. We find a new method to calcul…
The conformal boundary states for SU(2) at level 1
M. R. Gaberdiel, A. Recknagel, G. M. T. Watts
For the case of the SU(2) WZW model at level one, the boundary states that only preserve the conformal symmetry are analysed. Under the assumption that the usual Cardy boundary sta…
Minimal model boundary flows and c=1 CFT
K. Graham, I. Runkel, G. M. T Watts
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…
Finite size effects in perturbed boundary conformal field theories
P. Dorey, M. Pillin, A. Pocklington +3
We discuss the finite-size properties of a simple integrable quantum field theory in 1+1 dimensions with non-trivial boundary conditions. Novel off-critical identities between cyli…
One-point functions in perturbed boundary conformal field theories
P. Dorey, M. Pillin, R. Tateo +1
We consider the one-point functions of bulk and boundary fields in the scaling Lee-Yang model for various combinations of bulk and boundary perturbations. The one-point functions o…
On the boundary Ising model with disorder operators
G. M. T. Watts
We extend the well-known method of calculating bulk correlation functions of the conformal Ising model via bosonisation to situations with boundaries. Oshikawa and Affleck have fou…
A note on decoupling conditions for generic level and fusion rules
A. Ch. Ganchev, V. B. Petkova, G. M. T. Watts
We find the solution of the singular vector decoupling equations on 3-point functions for the particular case when one of the fields is of weight . T…
Non-unitarity in quantum affine Toda theory and perturbed conformal field theory
G. Takacs, G. M. T. Watts
There has been some debate about the validity of quantum affine Toda field theory at imaginary coupling, owing to the non-unitarity of the action, and consequently of its usefulnes…
