Interplay between freezing and density anomaly in a confined core-softened system

Soft Condensed Matter 2019-10-28 v1

Abstract

We present a computer simulation study of influence of the confinement on the density anomaly in the system with isotropic core-softened potential which is used for a qualitative description of the anomalous behavior of water and some other liquids. We have found that a maximum temperature of the density anomaly region along an isochor ρ=0.5\rho=0.5 does not depend on the pore width. We have shown that a decrease in the width of the confining slit pore leads to an increase in the crystallization temperature and as a result the local density distribution is mostly controlled by the particle-wall interaction, which leads to the depression of the density anomaly.
