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…
Schmid-Higgs Mode in the Presence of Pair-Breaking Interactions
Maxim Dzero, Alex Kamenev
Collective modes in superconductors provided the first realization of the Higgs mechanism. The transverse Goldstone mode acquires a gap (i.e. a mass) when it hybridizes with the el…
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…
Inverse Faraday effect in superconductors with potential impurities
Maxim Dzero
I consider a nonlinear response of conventional superconductors contaminated with potential impurities or imperfections to a circular polarized light. I focus on dc contributions t…
