Finite size effects in the SS-model: two component nonlinear integral equations
Arpad Hegedus
We derive a finite set of nonlinear integral equations for describing the finite size dependence of the ground state energy of the O(4) nonlinear sigma model. By modifying the kern…

TBA equations for excited states in the O(3) and O(4) nonlinear -model
J. Balog, A. Hegedus
TBA integral equations are proposed for 1-particle states in the sausage- and SS-models and their -model limits. Combined with the ground state TBA equations the exact mass gap…

TBA equations for excited states in the Sine-Gordon model
J. Balog, A. Hegedus
We propose TBA integral equations for multiparticle soliton (fermion) states in the Sine-Gordon (massive Thirring) model. This is based on T-system and Y-system equations, which fo…
