#include <chemicalpotential.h>

Struct, root equations, and procedure for finding the effective chemical potential for a given particle species.

This chemical potential is NOT the equilibrium chemical potential of a system with multiple particle species. Rather, it is the effective chemical potential of a particle species calculated as if only that species is present. (In particular, this applies also to particles and antiparticles of the same species.) Note that the procedure is exact for a system composed of protons and neutrons only, as their mass is degenerate. Struct object that holds the parameters relevant to finding the effective chemical potential of one particle species.
