Abstract:
We investigate the thermodynamic and dynamic properties of a three dimensional associating lattice gas (ALG) model through Monte Carlo simulations. The ALG model combines a soft core potential and orientational degrees of freedom. The competition of directional attractive forces and the soft core potential results in two coexisting liquid phases which are also connected through order-disorder critical transitions. The model presents structural order, density, and diffusion anomalies. Our study suggests that the dynamic fragile-to-strong transitions are associated to changes in structural order.
