The properties of many materials at the atomic scale depend on the electronic structure, which requires a quantum mechanical treatment. The most widely used approach to make such a treatment feasible is density functional theory (DFT), the advances in wh...

The self-interaction of a rossby normal mode in a rectangular basin is studied by means of an analytical and a numerical model. The analytical approach is based on perturbation methods. At first order in the nonlinearties, the self-interaction produces a...
