interband pairing interaction is considerably weaker than the intraband interactions. There is …

Microscopic derivation of two-component Ginzburg-Landau model and conditions of its applicability in two-band systems

M Silaev, E Babaev - Physical Review B—Condensed Matter and Materials …, 2012 - APS
We report a microscopic derivation of two-component Ginzburg-Landau (GL) field theory
and the conditions of its validity in two-band superconductors. We also investigate the …

Intertype superconductivity in ferromagnetic superconductors

A Vagov, TT Saraiva, AA Shanenko… - Communications …, 2023 - nature.com
In many pnictides the superconductivity coexists with ferromagnetism in an accessible range

Screening of pair fluctuations in superconductors with coupled shallow and deep bands: A route to higher-temperature superconductivity

L Salasnich, AA Shanenko, A Vagov, JA Aguiar… - Physical Review B, 2019 - APS
A combination of strong Cooper pairing and weak superconducting fluctuations is crucial to
achieve and stabilize high-T c superconductivity. We demonstrate that a coexistence of a …

Multiband material with a quasi-1D band as a robust high-temperature superconductor

TT Saraiva, PJF Cavalcanti, A Vagov, AS Vasenko… - Physical Review Letters, 2020 - APS
It is well known that superconductivity in quasi-one-dimensional (Q1D) materials is hindered
by large fluctuations of the order parameter. They reduce the critical temperature and can …
