Singularity confinement and chaos in discrete systems
Jarmo Hietarinta, Claude Viallet
We present a number of second order maps, which pass the singularity confinement test commonly used to identify integrable discrete systems, but which nevertheless are non-integrab…
Baryogenesis and the Thermalization Rate of Stop
Kari Enqvist, Antonio Riotto, Iiro Vilja
We take the first steps towards the complete computation of the thermalization rate of the supersymmetric particles involved in electroweak baryogenesis by computing the thermaliza…
Pure quantum integrability
Jarmo Hietarinta
The correspondence between the integrability of classical mechanical systems and their quantum counterparts is not a 1-1, although some close correspondencies exist. If a classical…
Introduction to the Hirota bilinear method
J. Hietarinta
We give an elementary introduction to Hirota's direct method of constructing multisoliton solutions to integrable nonlinear evolution equations. We discuss in detail how this works…
A note on the eight tetrahedron equations
Jarmo Hietarinta, Frank Nijhoff
In this paper we derive from arguments of string scattering a set of eight tetrahedron equations, with different index orderings. It is argued that this system of equations is the…
CP-Violation and Baryogenesis in The Low Energy Minimal Supersymmetric Standard Model
Tuomas P. Multamaki, Iiro Vilja
In the context of the minimal supersymmetric extension of the Standard Model the effect of a realistic wall profile is studied. It has been recently showed that in the presence of…
