Exact boundary flows in the tricritical Ising model
G. Feverati, P. A. Pearce, F. Ravanini
We consider the tricritical Ising model on a strip or cylinder under the integrable perturbation by the thermal boundary field. This perturbation induces five distinct re…
Excited Boundary TBA in the Tricritical Ising Model
G. Feverati, P. A. Pearce, F. Ravanini
By considering the continuum scaling limit of the RSOS lattice model of Andrews-Baxter-Forrester with integrable boundaries, we derive excited state TBA equations describin…
Nonlinear Integral Equation and Finite Volume Spectrum of Minimal Models Perturbed by
G. Feverati, F. Ravanini, G. Takacs
We describe an extension of the nonlinear integral equation (NLIE) method to Virasoro minimal models perturbed by the relevant operator $Φ_{(1,3)$. Along the way, we also complete…
Scaling Functions in the Odd Charge Sector of Sine-Gordon/Massive Thirring Theory
G. Feverati, F. Ravanini, G. Takacs
A non-linear integral equation (NLIE) governing the finite size effects of excited states of even topological charge in the sine-Gordon (sG) / massive Thirring (mTh) field theory,…
Truncated Conformal Space at c=1, Nonlinear Integral Equation and Quantization Rules for Multi-Soliton States
G. Feverati, F. Ravanini, G. Takacs
We develop Truncated Conformal Space (TCS) technique for perturbations of c=1 Conformal Field Theories. We use it to give the first numerical evidence of the validity of the non-li…
