1210.1661 (Artjom Vargunin et al.)

On intraband superconducting instability smeared by interband
interaction
   [PDF]

Artjom Vargunin, Küllike Rägo, Teet Örd
We study several manifestations of former intrinsic phase transition in the band with weaker superconductivity by analysing thermodynamics of a two-gap system. We show that weak interband interaction acts as external field on that critical point. At that, the corresponding singularities of the thermodynamic functions become smeared and all located at different temperatures.
