Breather decay into a vortex/antivortes pair in a Josephson ladder
Resumen: We present experimental evidence for a behavior which involves discrete breathers and vortices in a Josephson ladder. Breathers can be visualized as the creation and subsequent annihilation of vortex/antivortex pairs. An externally applied magnetic field breaks the vortex/antivortex symmetry and causes the breather to split apart. The motion of the vortex or antivortex creates multisite breathers, which are always to one side or the other of the original breather depending on the sign of the applied field. This asymmetry in the applied field is experimentally observed.
