Cyclotron resonance in ideal superconductors

Abstract
Cyclotron resonance in superconductors is examined on general grounds. It is demonstrated that Kohn’s theorem can be extended to the case of both type-I and type-II superconductors to within relativistic corrections. The relation of this result to vortex dynamics in superconductors, the Penning trap, and to hydrodynamics in general is discussed.
