Superfluid 3 He Josephson weak links

Josephson weak links between samples of macroscopic quantum systems such as superconductors, superfluids, and Bose-Einstein condensates provide a unique tool with which to explore quantum mechanics and an opportunity to create applications based on macroscopic quantum physics. In this review we describe the development of the field of weak links in superfluid 3 He. We review the basic technique...

Fabricating Nanoscale Aperture Arrays as Superfluid 4He Weak Links

Arrays of nanoscale apertures have been discovered to exhibit the characteristic signatures of so-called Josephson weak links in superfluid helium-4, 4He [1]. These devices can be used to detect quantum phase differences in a matter wave interferometer [2]. Thin (~ 60 nm) silicon nitride membranes were made by photolithography on silicon wafers and several varieties of aperture arrays shot on t...

Discrete breathers in Josephson arrays.

Since the original proposal of 1996 by Floria et al. [Europhys. Lett. 36, 539 (1996)] of intrinsic localization in Josephson ladders, many efforts have been devoted to the theoretical, numerical, and experimental study of such dynamical states in Josephson arrays. Such efforts have already produced around 20 papers on the subject. In this article we will try to review the basic aspects of the p...
