Magnetic Flux Periodicity of h/e in Superconducting Loops — •Florian Loder1, Thilo Kopp1, Arno Kampf1, Jochen Mannhart1, Christof Schneider1, and Yuri Barash21EKM, Institut für Physik, Universität Augsburg, 86135 Augsburg — 2Institute of Solid State Physics, Russian Academy of Sciences, Chernogolovka, Russia

We apply the BCS theory to superconducting rings with unconventional order parameter symmetries. An external magnetic flux changes the character of the states in the condensate; as a consequence the energy of the superconducting ground state varies with a flux period of h/e. This h/e periodicity is caused by the flux-induced reconstruction of the supercurrent carrying condensate.
