Phase fluctuations and vortex lattice melting in triplet quasi-one-dimensional superconductors at high magnetic fields

Abstract

Assuming that the order parameter corresponds to an equal spin triplet pairing symmetry state, we calculate the effect of phase fluctuations in quasi-one-dimensional superconductors at high magnetic fields applied along the y ${(b}^{\ensuremath{'}})$ axis. We show that phase fluctuations can destroy the theoretically predicted triplet reentrant superconducting state, and that they are responsible for melting the magnetic-field induced Josephson vortex lattice, above a magnetic-field dependent melting temperature ${T}_{m}.$
