Abstract
The electro-magnetostatic Aharonov-Bohm effect is shown to allow a full control of a Josephson junction. Both the sign and the magnitude of the supercurrent can be tuned if the junction between two superconductors is realized with a ring-shaped ballistic normal region. The implementation in a realistic set-up is discussed. (C) 2007 Elsevier B.V. All rights reserved.File in questo prodotto:
