Dear Lammps developer,
I was wondering if you could help me to implement a modified Tersoff potential in Lammps?
In the current tersoff/mod pair style, comparing to the cited paper (M.V.R. Murty, H.A. Atwater, Phys Rev B, 51, 4889 (1995)), it lacks of F1(N) and F2(N) terms in the equation. Is it possible to add these two terms in it?
F1(N) and F2(N) are functions of coordination number N. They are obtained by spline fit of discrete values with integer N number.
Thank you for your help!
