It processes the screening charge density σ on the surface of molecules to calculate the chemical potential µ of each species in solution.
If a point charge Q is placed at r = 0 in a solid, what field will it produce, taking electron screening into account? One seeks a self-consistent solution to two equations: • The Thomas–Fermi screening formula gives the charge density at each point r as a function of the potential at that point.
