Observation of a radiation-induced soliton resonance in a Josephson ring
Ustinov A.V.
Experimental study of single-soliton dynamic* in a ring-shaped Josephson junction is reported. An externally applied magnetic field Η forms a harmonic potential for the soliton in the ring. Rotation of the soliton in the junction leads to a potential-induced emission of plasma waves which give rise to a resonance at a certain soliton velocity. This behavior agrees with numerical simulations which indicate locking of the soliton to the radiation frequency. Good agreement between experiment, kinematic model and numerical simulations is found. ΡΑΓ!ςž (Μ 4ì Kf ðñ fi5 Pm 74 .40 -Lr
