Magnetically Stimulated Diffusion of Rydberg Gases

The specific kind of diffusion stimulated (rather than suppressed) by the external magnetic field, which was predicted for the first time by Schmelcher and Cederbaum in 1992, is considered here for the case of high-angular-momentum (i.e., approximately “circular”) Rydberg atoms. The coefficient of such diffusion was calculated by a purely analytical approach and was found to be well relevant to the experiments on antihydrogen formation.
