Supersymmetric integrable scattering theories with unstable particles
Andreas Fring
We propose scattering matrices for N=1 supersymmetric integrable quantum field theories in 1+1 dimensions which involve unstable particles in their spectra. By means of the thermod…
Chaos in the thermodynamic Bethe ansatz
Olalla Castro-Alvaredo, Andreas Fring
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 establ…
Exactly solvable potentials of Calogero type for q-deformed Coxeter groups
Andreas Fring, Christian Korff
We establish that by parameterizing the configuration space of a one-dimensional quantum system by polynomial invariants of q-deformed Coxeter groups it is possible to construct ex…
On vacuum energies and renormalizability in integrable quantum field theories
Olalla Castro-Alvaredo, Andreas Fring
We compute for various perturbed conformal field theories the vacuum energies by means of the thermodynamic Bethe ansatz. Depending on the infrared and ultraviolet divergencies of…
