Quantum density anomaly in optically trapped ultracold gases
Eduardo O. Rizzatti, Marco Aurelio A. Barbosa, Marcia C. Barbosa
We show that the Bose-Hubbard Model exhibits an increase in density with temperature at fixed pressure in the regular fluid regime and in the superfluid phase. The anomaly at the B…
Multiple liquid-liquid critical points and anomalies in core-softened potentials
Marco Aurélio A. Barbosa, Evy Salcedo, Marcia Barbosa
The relation between liquid-liquid phase transitions and waterlike density anomalies in core-softened potentials of fluids was investigated in an exactly solvable one dimensional l…
An ubiquitous mechanism for waterlike anomalies
Alan Barros de Oliveira, Paulo A. Netz, Marcia C. Barbosa
Using collision driven molecular dynamics a system of spherical particles interacting through an effective two length scales potential is studied. The potential can be tuned by mea…
Which mechanism underlies the water-like anomalies in core-softened potentials?
Alan Barros de Oliveira, Paulo A. Netz, Marcia C. Barbosa
Using molecular dynamics simulations we investigate the thermodynamic of particles interacting with a continuous and a discrete versions of a core-softened (CS) intermolecular pote…
Dynamic Anomalies of Fluids with Isotropic Doubled-Ranged Potential
Paulo Netz, J. F. Raymundi, Adriana S. Camera +1
Using molecular dynamics simulations we investigate the ability of an analytical three-dimensional double well in reproducing static and dynamic anomalies found experimentally in l…
Translational and Rotational Diffusion in Stretched Water
P. A. Netz, F. Starr, M. C. Barbosa +1
We perform molecular dynamics simulations using the extended simple point charge SPC/E water model in order to investigate the dynamical behavior of supercooled-stretched water. We…
