Gradient method for thermal phase transitions
N Boissin, Hans Jürgen Herrmann
The authors present a new numerical method of obtaining critical temperatures and exponents for ferromagnetic spin models and dynamical transitions. This method is based on the spreading of damage in a temperature gradient. They illustrate the method on the two-dimensional Ising model and present new results on the +or- Ising spin glass in two dimensions. They also obtain new critical exponents, describing the behaviour of the width and the length of the damage front.
