Liquid polymorphism, density anomaly and H-bond disruption in an associating lattice gases
Aline Balladares, Vera B. Henriques, Marcia C. Barbosa
We have investigated the effects of either distorting hydrogen bonds or removing proton degeneracy on the thermodynamic properties of a minimal model for associating liquids. The p…

Density Anomaly in Core-Softened Lattice Gas
Aline Lopes Balladares, Marcia C. Barbosa
A two dimensional lattice gas model with ''core-softened'' potential is investigated. Two liquid phases and density anomaly are found. The demixing phase transition between the two…
