The spin glass transition of the three dimensional Heisenberg spin glass.

We present our results[1] about the study of the critical properties of the three dimensions Edwards-Anderson model with Heisenberg spins, by means of Monte Carlo simulation and Finite Size Scaling analysis. A mixture of Heath Bath and Overrelaxation algorithms allowed us to thermalize lattices of size up to L=32. We have found a finite temperature transition where both the spin glass and the chiral glass orderings develop. The presence of logarithmic corrections suggests that the phase transition is of Kosterlitz-Thouless type, although we may not exclude a lower critical dimension barely smaller than three. \newline \newline [1] I.
