Cooper pair - Wikipedia, the free encyclopedia
In condensed matter physics, a Cooper pair is the name given to electrons that are bound together at low temperatures in a certain manner first described in 1956 by American physicist Leon Cooper. C...

A visual model of the Cooper pair attraction has a passing electron which attracts the lattice, causing a slight ripple toward its path. Another electron passing in the opposite direction is attracted to that displacement.

BCS theory - Wikipedia, the free encyclopedia
BCS theory is the first microscopic theory of superconductivity, proposed by Bardeen, Cooper, and Schrieffer in 1957 since the discovery of superconductivity in 1911. It describes superconductivity a...

We consider an array of lb Cooper pair boxes, each of which is coupled to a superconducting reservoir by a capacitive tunnel junction. We discuss two effects that probe not just the quantum nature of the islands, but also of the superconducting reservoir coupled to them.

However, the ground state of a superconducting island connected to superconducting reservoirs can be a coherent superposition of charge states differing by two electrons (i.e. a Cooper pair). We describe an experiment in which this Josephson effect involving only one Cooper pair is measured.

We propose an optical method to investigate the Cooper pair coherence across different regions of the superfluid. Near-resonant laser light is used to induce transitions between the two coupled hyperfine states. The beam is split so that it probes two spatially separate regions of the gas.

We present a series of measurements on nine single Cooper-pair boxes (SCBs), where the charging energy, EC, and the Josephson coupling energy, EJ, have been varied. We have investigated both the ground state properties of the SCBs and their quantum coherent properties.
