Abstract

We investigate the discretized version of the thermodynamic Bethe ansatz equation for a variety of (1+1)-dimensional quantum field theories. By computing Lyapunov exponents we establish that many systems of this type exhibit chaotic behaviour, in the sense that their orbits through fixed points are extremely sensitive with regard to the initial conditions.
