Résumé :
Deterministic dynamics in extended phase space of a constant temperature interacting spin system is formulated. The spin temperature is recovered thought constrained equation of motion and is in agreement of Rugh's geometrical approach to temperature for classical Heisenberg spin systems. Detailed comparisons are investigated between state-of-the-art stochastic spin dynamics and deterministic dynamics using a chain of thermostats, for which an accelerated convergence structure is found.
