Interplay between structure and density anomaly for an isotropic core-softened ramp-like potential
Alan Barros de Oliveira, Paulo A. Netz, Marcia C. Barbosa
Using molecular dynamics simulations and integral equations we investigate the structure, the thermodynamics and the dynamics of a system of particles interacting through a continu…
Water-like hierarchy of anomalies in a continuous spherical shouldered potential
Alan Barros de Oliveira, Giancarlo Franzese, Paulo A. Netz +1
We investigate by molecular dynamics simulations a continuous isotropic core-softened potential with attractive well in three dimensions, introduced by Franzese [cond-mat/0703681,…
Diffusion Anomaly in an Associating Lattice Gas Model
Marcia M. Szortyka, Marcia C. Barbosa
We investigate the relation between thermodynamic and dynamic properties of an associating lattice gas (ALG) model. The ALG combines a two dimensional lattice gas with particles in…
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…
Liquid Polymorphism and Density Anomaly in a Lattice Gas Model
Vera B. Henriques, Marcia C Barbosa
We present a simple model for an associating liquid in which polymorphism and density anomaly are connected. Our model combines a two dimensional lattice gas with particles interac…
Flexible Polyelectrolytes with Monovalent Salt
Paulo S. Kuhn, Marcia C. Barbosa
We present a model for describing flexible polyelectrolytes in a good solvent a nd in the presence of monovalent salt . The molecule composed by monomers is characterized by th…
