The role of phase fluctuations in model of superconductivity with the external pair potential
Konstantin V. Grigorishin ;
Date 30 Apr 2017
AbstractWe investigate the stability of the solutions of the BCS model with the external pair potential formulated in a work K.V. Grigorishin arXiv:1605.07080. It has been shown that the cause of superconductivity in this model is the electron-electron interaction only and the potential cannot impose superconductivity since the superconducting ordering will be destroyed by phase fluctuations in a form of quantum turbulence (vortexes, vortex rings, vortex tangles etc.). The external pair potential renormalizes the order parameter in initial superconducting matter and the bosonic scenario of transition to normal state in a clear 3D superconductor occurs unlike BCS theory where the fermionic scenario takes place.
