Lebedeva potential for anisotropic van der Waals interlayer interaction in graphene.


Zbigniew Kozioł, National Center for Nuclear Research, Otwock-Świerk, Poland

Backward Compatibility

No backward compatibility is broken.

Implementation Notes

The code is written in an analogy to the code for Kolmogorov-Crespi potential. Compilation goes the same way as for Kolmogorov-Crespi. Values of potential and it's derivatives were tested for consistency between results obtained in LAMMPS by comparing them with these obtained with Lennard-Jones and Kolmogorov-Crespi models. The code was tested also by I. Lebedeva and her co-workers. Other features of LAMMPS functionality are not affected.

@zbych127 thanks for your perseverance. this looks good. however, you will have to wait a couple of weeks or so before it will be merged, since we are currently in bugfix-only mode in preparation for the next stable release. please stay tuned...
