SUMMARY:Applied Math Seminar - Shibin Dai
DESCRIPTION:Phase-Field Free Energy and Boundary Force for Molecular Solvation\n\nAbstract:\n\nWe discuss a phase-filed variational model for the solvation of charged molecules with implicit solvent. The solvation free-energy functional of all phase fields consists of the surface energy\, solute excluded volume and solute-solvent van der Waals dispersion energy\, and electrostatic free energy. The last part is defined through the electrostatic potential governed by the Poisson-Boltzmann equation in which the dielectric coefficient is defined through a phase field. We prove Gamma- convergence of the phase field free-energy functional to its sharp-interface limit. We also define the dielectric boundary force for any phase field as the negative first variation of the free-energy functional\, and prove the convergence of such force to the corresponding sharp-interface limit.
