@article{1021, author = {Homer Reid and Alejandro Rodriguez and Jacob White and Steven Johnson}, title = {Efficient computation of Casimir interactions between arbitrary three-dimensional objects}, abstract = {We introduce an efficient technique for computing Casimird energies and forces between ob jects of arbitrarily complex 3D geometries. In contrast to other recently developed methods, our technique easily handles non-spheroidal, non-axisymmetric ob jects and ob jects with sharp corners. Using our new technique, we obtain the first predictions of Casimir interactions in a number of experimentally relevant geometries, including crossed cylinders and tetrahedral nanoparticles.}, year = {2009}, journal = {PRL}, volume = {103}, number = {4}, pages = {040401}, url = {http://link.aps.org/doi/10.1103/PhysRevLett.103.040401}, note = {Invited paper to \emphVirtual Journal of Nanoscale Science and Technology, August 3, 2009}, }
