Question regarding lcbop potential

Dear Lammps usears,
I have a question about lcbop implementation in lammps and any helps is appreciated.
To simulate a system of carbons with lcbop potental,According to the Lammps documentation, this pair potential requires the newton setting to be “on” for pair interactions.
Does this mean in simulation with this forcefield I have to always use this input

pair_style lcbop
pair_coeff * * ../potentials/C.lcbop C
newton on

I mean I am a bit confused about the pair and bond interaction for a pure carbon system here,

thanks in advance


can you be a bit more specific what exactly you are confused about?
