Phase stiffness in flat-band superconductors with nodal pairing
A. A. Zyuzin, A. Yu. Zyuzin
We study Bogoliubov quasiparticle spectrum in a two-band system with momentum-dependent hybridization between a dispersive band and a flat band. The interplay between the interband…

Superconductivity from incoherent Cooper pairs in the strong-coupling regime
A. A. Zyuzin, A. Yu. Zyuzin
We propose a scenario for superconductivity at strong electron-electron attractive interaction, in the case when the increase of the interaction strength promotes the nucleation of…

Magnetoelectric effect in superconductors with d-wave magnetization
Alexander A. Zyuzin
We report on a study of the interplay between the supercurrent and spin-polarization in a two-dimensional superconducting system in the presence of a d-wave symmetric antiferromagn…
