Compressibility and pressure correlations in isotropic solids and fluids

Abstract

Presenting simple coarse-grained models of isotropic solids and fluids in $d=1$, $2$ and $3$ dimensions we investigate the correlations of the instantaneous pressure and its ideal and excess contributions at either imposed pressure (NPT-ensemble, $\lambda =0$) or volume (NVT-ensemble, $\lambda =1$) and for more general values of the dimensionless parameter $\lambda$ characterizing the constant-volume constraint.
