 For a careful theoretical understanding, one has to investigate the exact model parameters that are employed. The equation of state follows the form  (Eq. 45 of [[https://arxiv.org/pdf/1908.11258.pdf|Camelio et al., 2019]]):  For a careful theoretical understanding, one has to investigate the exact model parameters that are employed.
