Abstract
A new theory of neoclassical transport in the presence of an asymmetric separatrix between trapped and passing particles is discussed, and tested using simulations and experiments. The theory, simulations, and experiments are presented for the geometry of a nonneutral plasma, but it can be applied to understand tokamak and stellarator confinement, where asymmetries in the separatrices between trapped and passing particles are ubiquitous.
