Nonlinear integral equations for the finite size effects of RSOS and vertex-models and related quantum field theories
Arpad Hegedus
Starting from critical RSOS lattice models with appropriate inhomogeneities, we derive two component nonlinear integral equations to describe the finite volume ground state energy…

TBA equations for the mass gap in the O(2r) non-linear sigma-models
J. Balog, A. Hegedus
We propose TBA integral equations for 1-particle states in the O(n) non-linear sigma-model for even n. The equations are conjectured on the basis of the analytic properties of the…
