Description

Calculations of equation of state of QCD become reliable at the densities of around 40 saturation densities. These densities are well beyond those that are reached within the cores of even the most massive neutron stars. However, knowing the equation state at these extreme densities still gives us robust information at lower densities because of global requirements imposed by causality, stability and thermodynamical consistency. In my talk I will demonstrate that due to these general physics conditions, the current state-of-the-art perturbative calculations constrain the equation of state even down to 2.3 saturation densities.
