title: Spontaneous synchronization in a Josephson transmission line.
abstract: At high frequencies, the dynamics of a Josephson array shows fundamental differences from its low-frequency behavior. We consider a simple array where the high-frequency effects are dominant, a current biased series array without any external load. Despite the absence of a load, the oscillators are dynamically coupled at high frequencies, and synchronized states can be attracting. We investigate the character and stability of the synchronized states.
