Critical Casimir force scaling function of the mean spherical model — •Boris Kastening and Volker Dohm — Institut für Theoretische Physik, RWTH Aachen
Motivated by recent unexplained experimental data [1,2] concerning the scaling function of the critical Casimir force in Helium films below Tλ, we carry out an analysis of the finite-size scaling functions of the excess free energy and of the critical Casimir force within the mean spherical model below Tc in film geometry with d−1 infinitely extended dimensions and one direction of finite extent. We consider various boundary conditions.
