In the input file, I used real units. However, I read the original paper of airebo and they used eV unit for epsilon.
So, my question is, if I want to use airebo potential in real units, do I need to change the three epsilon number for kCal/mol or I just need to do nothing and lammps will change it automatically for me?
For example. the first number 0.0028eV equals to 0.0644kCal/mol.
