Fluctuation induced interactions between dielectrics in general geometries

Tony Maggs (ESPCI, Paris)

par Webmaster - 27 juin 2007

We study thermal Casimir and quantum non-retarded Lifshitz interactions between dielectrics in non-planar geometries. We map the calculation of the classical partition function onto a determinant which we discretize and evaluate with Cholesky factorization. We demonstrate the non additivity of interaction between a sharp point and a surface indentation and calculate a free energy landscape for a structured surface.
