Particle Properties
The particle properties input file is optional. Provide the path using the particle_properties_input_file if you are not using the Calculation Engine, and enable the output_particle_properties option in the config file to generate its output.
Since this file does not have requirements, the output will have the same columns as the input file, plus the lepton densities, chemical potentials, and masses appended at the end as:
Variable |
Unit |
|---|---|
Electron chemical potential (\(\mu_e\)) |
MeV |
Neutrino chemical potential (\(\mu_{\nu}\)) |
MeV |
Electron density (\(n_e\)) |
fm-3 |
Muon density (\(n_{\mu}\)) |
fm-3 |
Tau density (\(n_{\tau}\)) |
fm-3 |
Neutrino density (\(n_{\nu}\)) |
fm-3 |
Electron mass (\(m_e\)) |
MeV |
Muon mass (\(m_{\mu}\)) |
MeV |
Tau mass (\(m_{\tau}\)) |
MeV |
Neutrino mass (\(m_{\nu}\)) |
MeV |
One can generate the charge_neutrality_particle_properties.csv or the beta_equilibrium_particle_properties.csv file by enabling the output_particle_properties option in the config file in addition to the use_charge_neutrality or use_beta_equilibrium options, respectively. In the beta-equilibrated case, the input file will be interpolated to give the value of the quantities at the beta-equilibrated point.
For the purely Leptonic EoS, the associated particle properties follows:
