CeO2 ( potential )

Hi lammps users
I want to know that core-shell model can be possible in LAMMPS?!

LAMMPS has the right potential (Coulomb +  
Buckingham), but I haven't seen any documentation where this can be  
used for the polarizable core/shell, while also accounting for the  
harmonic potential that governs interactions between each core and  
shell.
E(core-shell)=1/2*K*r^2
K[ev.A^-2]
r[A]

how can i generate a new potential in lammps? 
who has experienced with ( shell model ) potential?
please give me some point

Thnx a lot

it is always a good idea to start by reading the documentation:

I think I already answered your Q in another thread.

Several people have worked on a core/shell model for
LAMMPS, but no one has sent us code to release. So
please search the mail list for core/shell and send them
an email.
