It is not easy to find the forces written down for embedded atom model.
The potential is always written as
Probably the reason for forces written down is that different fitting functions for , , are used depending on the researcher. For this reason, LAMMPS uses splines for their implementation.
As usual, the force is calculated by
Cai and Ye suggest the following forms will in the following forms (with derivatives added by me). Note that we have replaced with a more compact notation given by .
