Original · EN
In this paper I show how to calculate the effect of a nearby Pearl vortex or antivortex upon the critical current Ic(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 Λ= 2λ²/d, where λ is the London penetration depth and d is the thickness (d < λ). The theoretical results provide a qualitative explanation of unusual features recently observed experimentally by Golod et al.Golod10 in a device with a similar geometry.
