| Abstract | In this paper I show how to calculate the effect of a nearby Pearl vortex or antivortex upon the critical current I(c)(B) when a perpendicular magnetic induction B is applied to a planar Josephson junction in a long, thin, superconducting strip of width W much less than the Pearl length Lambda = 2 lambda(2)/d, where lambda is the London penetration depth and d is the thickness (d < lambda). The theoretical results provide a qualitative explanation of unusual features recently observed experimentally by Golod et al. [Phys. Rev. Lett. 104, 227003 (2010)] in a device with a similar geometry. |
