ABSTRACT

A busy junctionJosephson effects, in which currents 'tunnel' across a thin insulating barrier, were first discovered in a system of two superconductors, the macroscopic wavefunctions of which are weakly coupled via a tunnelling barrier. Bose–Einstein condensates (BECs) are also expected to support Josephson effects, but a clear observation remained elusive. Levy et al. now report the observation of a.c. and d.c. Josephson effects in a single BEC Josephson junction. The system may be suitable for use as an analogue of the superconducting quantum interference device (SQUID), able to sense rotation. More... »
