Giant Variations of Cooper-Pair Size in Nanoscale Superconductors
A. A. Shanenko, M. D. Croitoru, A. Vagov +1
The Cooper-pair size (i.e., the BCS coherence length) in low-dimensional superconductors is dramatically modified by quantum-size effects. In particular, for nanowires made of conv…
Magnetic-field induced quantum-size cascades in superconducting nanowires
A. A. Shanenko, M. D. Croitoru, F. M. Peeters
In high-quality nanowires, quantum confinement of the transverse electron motion splits the band of single-electron states in a series of subbands. This changes in a qualitative wa…
Size-dependent enhancement of superconductivity in nanowires
A. A. Shanenko, M. D. Croitoru, M. Zgirski +2
A shape-dependent superconducting resonance can be expected when an energy level associated with the transverse motion in a wire passes through the Fermi surface. We show that the…
Shape resonances in the superconducting order parameter of ultrathin nanowires
A. A. Shanenko, M. D. Croitoru
We study the shape resonance effect associated with the confined transverse superconducting modes of a cylindrical nanowire in the clean limit. Results of numerical investigations…
Bound pair states beyond the condensate for Fermi systems below T_c: the pseudogap as a necessary condition
A. Yu. Cherny, A. A. Shanenko
As is known, the 1/q^2 theorem of Bogoliubov asserts that the mean density of the fermion pair states with the total momentum q obeys the inequality n_q > C/q^2 (q \to 0) in the ca…
