Phys. Rev. B 74, 144502 (2006) [6 pages]Transition from synchronous to asynchronous superfluid phase slippage in an aperture arrayReceived 30 August 2006; published 5 October 2006 We have investigated the dynamics of superfluid phase slippage in an array of apertures. The magnitude of the dissipative phase slips shows that they occur simultaneously in all the apertures when the temperature is near Tλ−T≈10 mK and subsequently lose their simultaneity as the temperature is lowered. We describe three experiments to probe the mechanisms underlying the synchronous behavior. The results raise fundamental questions about the dynamics of phase slippage in a multiply connected geometry. © 2006 The American Physical Society URL:
