Manifestations of impurity induced ±⇒++ transition: multiband model for dynamical response functions
Publikováno v:
New journal of physics, 15(1):013002. IOP Publishing Ltd.
We investigate the effects of disorder on the density of states, the single-particle response function and optical conductivity in multiband superconductors with s± symmetry of the order parameter, where s± ⇒ s++ transition may take place. In the

We report the full complex dielectric function of high-purity Ba0.68K0.32Fe2As2 single crystals with Tc=38.5K determined by wideband spectroscopic ellipsometry at temperatures 10≤T≤300K. We discuss the microscopic origin of superconductivity-indu

We have reexamined the problem of disorder in two-band superconductors, and shown within the framework of the T-matrix approximation, that the suppression of T_c can be described by a single parameter depending on the intraband and interband impurity

The specific heat of high-purity Ba0.68 K0.32 Fe2 As2 single crystals with the highest reported superconducting Tc =38.5 K was studied. The electronic specific heat Cp below Tc shows two gap features, with Δ1≈11 meV and Δ2≈3.5 meV obtained from

We consider a two-band superconductor with relative phase π between the two order parameters as a model for the superconducting state in ferropnictides. Within this model we calculate the microwave response and the NMR relaxation rate. The influence
