Magnetic Flux Annihilation in a Large Josephson Junction.

Abstract

Recent developments in the theory of the sine-Gordon equation are used to analyze the appearance of a displaced linear branch in the voltampere characteristic of a large Josephson junction. Internally the junction is divided into a flux annihilation domain near the center and flux flow domains near the edges. The displaced linear branch is experimental evidence for the existence of flux flow domains. In the flux annihilation domain, an ac voltage component is induced by the continuous formation and decay of sine-Gordon breathers. Whitham's nonlinear WKB method is used to analyze the flux flow domains while the inverse scattering transform method is used as a qualitative guide to the study of breather formation in the flux annihilation domain.
