Fate of quasiparticles in the superconducting state

Abstract

Quasiparticle properties in the superconducting state are masked by the superfluid and are not directly accessibleto infrared spectroscopy. We show how one can use a Kramers–Kronig transformation to separate the quasiparticlefrom superfluid response and extract intrinsic quasiparticle properties in the superconducting state. We alsoaddress the issue of a narrow quasiparticle peak observed in microwave measurements, and demonstrate how itcan be combined with infrared measurements to obtain a unified picture of electrodynamic properties of cupratesuperconductors.
