Rossby wave equilibria and zonal jets
Peter B. Weichman
The problem of coherent vortex and zonal jet formation in a system of nonlinear Rossby waves is considered from the point of view of the late time steady state achieved by free dec…

Chern numbers and localization by non-Hermitean operators
J. Miller, P. B. Weichman
In Hermitean quantum mechanics, extended current-carrying states are distinguished from localized ones by their non-zero Chern number. We generalize the notion of Chern number to n…
