[lammps-users] multiple atom styles ?

I would like to have two groups of atoms; one that maintains ~6KB of data per atom in addition to the velocities, positions, etc…, and another that does not.
To implement this I would like to have two atom styles, via the atom_style command, and assign one atom_style to each type of atoms. The purpose of this approach is to store only the ‘needed’ data for an atom and avoid the costs associated with maintaining ‘unused’ data.

Is there a mechanism in LAMMPS to do this?

nope - the atom_style hybrid will store all info for multiple
styles for each atom - doing what you suggest would be
considerably more complicated
