Pairwise interaction potential between lipid particles. (a) Comparison with the Lennard-Jones (LJ6-12) potential. (b) The interaction potential profile as a function of $A\left(\alpha ,a\right)$. (c) Increase in the value of the parameter R_cut widens the potential well, giving rise to a softer core of the interparticle interaction $\left(A\left(\alpha ,a\right)=+1\right)$. The soft core is essential for stabilization of the membrane at the fluid phase.
