Amplitude mode in Eliashberg superconductors
Maxim Dzero, Emil A. Yuzbashyan
In the BCS theory of superconductivity the amplitude (Higgs) mode is degenerate with the pair-breaking threshold: its frequency coincides with , so it is an edge singularity ra…
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…
Collective modes in terahertz field response of superconductors with paramagnetic impurities
Yantao Li, Maxim Dzero
We consider a problem of nonlinear response to an external electromagnetic radiation of conventional disordered superconductors which contain a small amount of weak magnetic impuri…
