Abstract

The cooling of systems into a supercooled liquid state was studied using a kinetic Ising model with thermaly activated transition rates. A fictive temperature describing the state of the system was defined and the effects of different cooling rates on this temperature determined. Transitions of the different spins were independent in one of the model systems. Transition in the other system needed to be facilitated by the presence of adjacent up spins.
