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…
Completeness of the Bethe Ansatz solution of the open XXZ chain with nondiagonal boundary terms
Rafael I. Nepomechie, Francesco Ravanini
A Bethe Ansatz solution of the open spin-1/2 XXZ quantum spin chain with nondiagonal boundary terms has recently been proposed. Using a numerical procedure developed by McCoy et al…
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,…
Nonlinear Integral Equation and Finite Volume Spectrum of Sine-Gordon Theory
G. Feverati, F. Ravanini, G. Takacs
We examine the connection between the nonlinear integral equation (NLIE) derived from light-cone lattice and sine-Gordon quantum field theory, considered as a perturbed c=1 conform…
