Discrete spin variables and critical temperature in deterministic models with glassy behavior
The problem of the existence of a glassy phase transition in deterministic spin models is reconsidered, examining an Ising model with general spin s and nontranslationally invariant interaction. The discrete nature of the spin variables is shown to allow the glass state.
