| dc.description | In this paper, we explain the fundamental properties of the radiation processess of untrapped kinks moving on discrete lattices or any spatially periodic potential. In particular we explain qualitatively and quantitatively the interesting recent experiments of small discrete periodic dynamical arrays of Josephson junctions. We obtain and show the resonance condition for a kink to radiate phonons is the kink frequency or one of its harmonics K_j$\dot{X}$ where $\dot{X}$ is the velocity of the kink and the K_j are vectors of the reciprocal lattice must equal one of the phonon frequencies, $ω(k)$, where k are the lattice vectors determined by the lattice spacing and the periodic boundary conditions. Then we show the radiation resonance conditions determine the voltage at line center in the experimental currently voltage (I-V) diagrams. | |
