Phys. Rev. Lett. 75, 1190–1193 (1995)Glassiness in a Model without Energy BarriersReceived 24 April 1995; published in the issue dated 7 August 1995 We propose a microscopic model without energy barriers in order to explain some generic features observed in structural glasses. The statics can be exactly solved while the dynamics has been clarified using Monte Carlo calculations. Although the model has no thermodynamic transition, it captures some of the essential features of real glasses, i.e., extremely slow relaxation, time dependent hysteresis effects, anomalous increase of the relaxation time, and aging. This suggests that the effect of entropy barriers can be an important ingredient to account for the behavior observed in real glasses. © 1995 The American Physical Society URL:
