Glassy behavior in a ferromagnetic p-spin model

Recent work has suggested the existence of glassy behavior in a ferromagnet ic model with a four-spin interaction. Motivated by these Endings, we have studied the dynamics of this model using Monte Carlo simulations with parti cular attention being paid to two-time quantities. We find that the system shares many features in common with glass forming liquids. In particular, t he model exhibits (i) a very long-lived metastable state, (ii) autocorrelat ion functions that show stretched exponential relaxation, (iii) a nonequili brium time scale that appears to diverge at a well defined temperature, and (iv) low temperature aging behavior characteristic of glasses.
