Abstract

At high magnetic field, the semiclassical approximation which underlies the Ginzburg-Landau theory of the mixed state of type-II superconductors breaks down. In a quasi-one-dimensional superconductor with an open Fermi surface, a high magnetic field stabilizes a cascade of superconducting phases which ends in a strong reentrance of the superconducting phase. From a microscopic mean-field model, we determine the thermodynamics and the excitation spectrum of these quantum superconducting phases.
