The giant squid (Dosidicus gigas) lives mainly in the oceanic environment, but also occurs in neritic (relatively shallow) environments, and makes horizontal and vertical migrations. It is a physiologically tolerant species, characterized by opportunistic consumption habits and is also considered an ecologically important species, acting as predator and prey of a large number of species (includ...

We have succeeded in the first demonstration of a simple and accurate resonator-superconducting quantum interference device (SQUID) coupling for microwave SQUID multiplexers. A simple theory shows our direct coupling with adjustable fractional inductance in the SQUID loop can decrease the deviation of resonance frequencies from designed values in contrast to a conventional inductive coupling. O...

We have investigated the rf SQUID (radio-frequency superconducting quantum interference device) and its coupling to tank circuit configurations to achieve an optimal front-end assembly for sensitive and high spatial resolution magnetic imaging systems. The investigation of the YBCO rf SQUID coupling to the conventional LC tank circuits revealed that coupling from the back of the SQUID substrate...

We describe a new type of scanning probe microscope based on a superconducting quantum interference device (SQUID) that resides on the apex of a sharp tip. The SQUID-on-tip is glued to a quartz tuning fork which allows scanning at a tip-sample separation of a few nm. The magnetic flux sensitivity of the SQUID is 1.8 μΦ(0)/√Hz and the spatial resolution is about 200 nm, which can be further impr...

We report the creation of a pair of Josephson junctions on a toroidal dilute gas Bose-Einstein condensate (BEC), a configuration that is the cold atom analog of the well-known dc superconducting quantum interference device (SQUID). We observe Josephson effects, measure the critical current of the junctions, and find dynamic behavior that is in good agreement with the simple Josephson equations ...

This paper describes a superfluid analog of the superconducting RF SQUID.1 Whereas an RF SQUID is sensitive to magnetic flux, the 4He SQUID (Superfluid QUantum Interference Device) is sensitive to absolute rotation. The device described here exhibits several of the characteristic phenomena of SQUIDs. For example: There is a "staircase" response function. The slope of the staircase response is d...
