Finite-momentum coupling of Higgs and Bardasis--Schrieffer modes in superconductors with competing pairing channels
Samuel Awelewa, Yafis Barlas, Maxim Dzero
In superconductors with competing pairing channels, two well defined excitations exist below the pair-breaking edge: the Higgs mode of the condensed -wave channel and the Bardas…

Quasiclassical theory of nonlinear response in d-wave superconductors
Aidan Steineman, Samuel Awelewa, Maxim Dzero
We use a self-consistent Keldysh--Nambu quasiclassical theory to study two related nonlinear phenomena in clean d-wave superconductors: the photo-induced static correction to the o…

Magnetic impurities in a strongly coupled superconductor
Samuel Awelewa, Maxim Dzero
We revisit certain aspects of a problem concerning the influence of carrier scattering induced by magnetic impurities in metals on their superconducting properties. Superconductivi…
