CEM equation of state in a tabulated format
Cluster expansion model (CEM) is a lattice-based model for the QCD equation of state at finite baryon densities. See more info here and here. It is provided here in a tabulated form.

The archive contains three files: CEMmini.dat
, CEMsmall.dat
, and CEMbig.dat
.
All files have the same format and correspond to different ranges of tabulated energy and baryon number densities. The table format is the following:
- Temperature [MeV]
- Baryochemical potential [MeV]
- Energy density in units of $e_0$, where $e_0$ = 0.14651751415742 GeV/fm$^3$
- Pressure in units of $e_0$, where $e_0$ = 0.14651751415742 GeV/fm$^3$
- Baryon number density in units of $n_0$, where $n_0$ = 0.15891 fm$^{-3}$
- Entropy density in units of $n_0$, where $n_0$ = 0.15891 fm$^{-3}$
- $\mu_S$ [MeV], here equals zero everywhere
- Auxialiary column for UrQMD stuff, which is not used here and filled with 1
