Two-band superconductors: hidden criticality deep in the superconducting state.
We show that two-band superconductors harbor hidden criticality deep in the superconducting state, stemming from the critical temperature of the weaker band taken as an independent system. For sufficiently small interband coupling γ the coherence length of the weaker band exhibits a remarkable deviation from the conventional monotonic increase with temperature, namely, a pronounced peak close t...
متن کاملType-1.5 superconducting state from an intrinsic proximity effect in two-band superconductors.
We show that in multiband superconductors, even an extremely small interband proximity effect can lead to a qualitative change in the interaction potential between superconducting vortices by producing long-range intervortex attraction. This type of vortex interaction results in an unusual response to low magnetic fields leading to phase separation into domains of two-component Meissner states ...
متن کاملSuperconducting properties of the s ±-wave state: Fe-based superconductors.
Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been settled with consensus with regard to the pairing symmetry and the superconducting (SC) gap function, the vast majority of experiments support the existence of spin-singlet sign-changing s-wave SC gaps on multi-bands ([Formula: see text]-wave state). This multi-band [Formula: see text]-wave state is a very uniqu...
متن کاملMagnetic properties of the superconducting state of iron-based superconductors
We show that features of the dynamical spin susceptibility can unambiguously distinguish between different pairing symmetries of the superconducting state in iron-based superconductors. A magnetic resonance is a feature for the extended sx2y2-wave cos kx cos ky pairing symmetry. It is present in the pure superconducting SC state but weakens in the mixed SC and magnetically ordered state. We cal...
