Roaming form factors for the tricritical to critical Ising flow
D. X. Horvath, P. E. Dorey, G. Takacs
We study the massless flows described by the staircase model introduced by Al.B. Zamolodchikov through the analytic continuation of the sinh-Gordon S-matrix, focusing on the renorm…
Confinement in the q-state Potts model: an RG-TCSA study
M. Lencses, G. Takacs
In the ferromagnetic phase of the q-state Potts model, switching on an external magnetic field induces confinement of the domain wall excitations. For the Ising model (q = 2) the s…
Excited state TBA and renormalized TCSA in the scaling Potts model
M. Lencses, G. Takacs
We consider the field theory describing the scaling limit of the Potts quantum spin chain using a combination of two approaches. The first is the renormalized truncated conformal s…
Finite volume form factors in the presence of integrable defects
Z. Bajnok, F. Buccheri, L. Hollo +2
We developed the theory of finite volume form factors in the presence of integrable defects. These finite volume form factors are expressed in terms of the infinite volume form fac…
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…
Spectral expansion for finite temperature two-point functions and clustering
István M. Szécsényi, Gábor Takács
Recently, the spectral expansion of finite temperature two-point functions in integrable quantum field theories was constructed using a finite volume regularization technique and t…
Form-factors of the sausage model obtained with bootstrap fusion from sine-Gordon theory
Z. Horvath, G. Takacs
We continue the investigation of massive integrable models by means of the bootstrap fusion procedure, started in our previous work on O(3) nonlinear sigma model. Using the analogy…
Free field representation for the O(3) nonlinear sigma model and bootstrap fusion
Zala'n Horva'th, Ga'bor Taka'cs
The possibility of the application of the free field representation developed by Lukyanov for massive integrable models is investigated in the context of the O(3) sigma model. We u…
