- W2064522759 abstract "In a recent paper, Faetti proposed a new phenomenological expression for the surface free energy density Fs of a nematic liquid crystal m contact with an isotropic substrate. Fs depends on director n, on the unit vector k orthogonal to the interface and on their gradients at the interface. Five different terms appear in the expression of Fs. The first term is the standard anchoring energy contribution, the second and third terms are elastic contributions that depend on the surface tangential director gradients, the fourth and fifth terms are new geometrical contributions that account for the effect of a local curvature of the interfaces. The expression of the surface free energy density is characterized by five phenomenological functions W(nk), K13(nk), K14(nk), Ai(nk) and A2(nk) where nk is the scalar product n. k. In this paper we give the first microscopic calculation of these new surface functions by using a simplified microscopic model of intermolecular interactions. Surface functions Ai(nk), A2(nk), and K14(nk) are found to be of the same order of magnitude of the Frank bulk elastic constants, whilst K13(nk) = 0. The geometric surface functions Ai(nk) and A2(nk) satisfy the simple relation Ai(nk) = -n( A2(nk). Both the results K13(nk) = 0 and Ai(nk) = -n( A2(nk) are shown to be a direct consequence of the invariance with respect to the transform n - -n of the interaction energy between molecules." @default.
