I want to use a potential joined with ZBL and polynomial in LAMMPS. The potential is given by
F®= p5r^5+p4r4^4+p3r^3+p2r^2+p1*r+p0 r1<=r<r2
Where Fc® is a cut-off function, given by
I want to know is there a suitable pair_style to describe the polynomial and the long-range part of potential? or I could only use the pair_style table to fit the potential into LAMMPS.
