Now, suppose the
Cooper pair charge velocity is constant at the two adjacent points; then the last integral quantity measures the difference in the interaction energy [delta][W.sub.int] between the
Cooper pairs and the vector potential at the two points:
These eigenmodes represent collective oscillations of the direction of total angular momenta of
Cooper pairs which generate fluctuations of axial currents in the superfluid system (spin density fluctuations).
Cooper pairs spatially confined to a single superconducting island in a JJA exhibit local coherence of the wave function phase.
Because the dynamics of
Cooper pairs in doped carbon nanotubes can be more close to the diffusive regime, the Usadel equations can be applied to calculate the finite conductivity at T [much less than] [T.sub.c] [19].
Researchers working in physics, from the US, Europe, Brazil, Mexico, and Japan discuss
Cooper pairs, superconductivity in highly correlated systems, the behavior of the Bose Einstein condensation critical temperature, the plasmon exchange model in carbon nanotubes, thermodynamic properties of point node superconductors, theory of the thermopower in YBCO, high-temperature superconductivity in carbon nanotubes, and magnetism and quark matter.
In addition, Perez-Enriquez [7], while working on high-Tc superconductivity, found that by using a Mobius-type orbital for
Cooper pairs, there is a structural parameter in perovskite type superconductors that correlates linearly with the critical temperature.
The superconducting analogs of these devices, in which electrons are bound in "
Cooper pairs" of charge 2 e, are attractive for two reasons.
The quantum state of the first qubit, which is defined by the number of superconducting electron pairs (also known as
Cooper pairs) contained in it, was first transferred to a microwave photon of a resonator using very precisely controlled microwave pulses.
Unlike
Cooper pairs, these coupled electrons did not coordinate their movements, Levy says.
