Greetings,
I would like to calculate the Gibbs free energy using the Frenkel-Ladd path and the nonequilibrium implementation suggested by Freites et al. (2016) in this paper. I found that the free energy perturbation can be done using the fix ti/spring
command in lammps. My question is, can this be used for any type of crystallin, including inclusion compounds like gas hydrates with any specific potential function (say SW potential)?
