Abstract
The specific heat of one lattice animal is computed using a new Monte Carlo approach. The specific heat exhibits a peak near the collapse transition temperature derived by Derrida and Herrmann. There is also a secondary, low temperature peak which appears to be associated with a roughening transition.
Résumé
En utilisant une nouvelle forme de la méthode Monte Carlo, nous calculons la chaleur spécifique d'un animal sur réseau. La chaleur spécifique présente un maximum au voisinage de la température d'effondrement obtenue par Derrida et Herrmann. Elle a aussi un maximum secondaire à basse temperature, liée, apparemment, à une transition rugueuse.
