Whispering Vortices

Wallraff, A.; Ustinov, A. V.; Kurin, V. V.; Shereshevsky, I. A.; Vdovicheva, N. K.

Experiments indicating the excitation of whispering-gallery-type electromagnetic modes by a vortex moving in an annular Josephson junction are reported. At relativistic velocities the Josephson vortex interacts with the modes of the superconducting stripline resonator giving rise to novel resonances on the current-voltage characteristic of the junction. The experimental data are in good agreement with analysis and numerical calculations based on the two-dimensional sine-Gordon model.
