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…
Spatially resolved collective modes in d-wave superconductors
Kazi Ranjibul Islam, Samuel Awelewa, Andrey V. Chubukov +1
We analyze the dispersion of collective modes in a superconductor with wave symmetry of the order parameter in the presence of long-range Coulomb interaction. We use diagrammat…
Dynamics of the Schmid-Higgs Mode in -wave superconductors
Samuel Awelewa, Maxim Dzero
We study the dynamics of the longitudinal collective mode in an unconventional superconductor. For concreteness, we assume that the superconductor is described by a -wave order…
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…
Migdal-Eliashberg superconductivity in a Kondo lattice
Samuel Awelewa, Maxim Dzero
We apply the Migdal-Eliashberg theory of superconductivity to heavy-fermion and mixed valence materials. Specifically, we extend the Anderson lattice model to a case when there exi…
