Query: The fate of quasiparticles in the superconducting state   Quasiparticle properties in the superconducting state are masked by the
superfluid and are not directly accessible to infrared spectroscopy. We show
how one can use a Kramers--Kronig transformation to separate the quasiparticle
from superfluid response and extract intrinsic quasiparticle properties in the
superconducting state. We also address the issue of a narrow quasiparticle peak
observed in microwave measurements, and demonstrate how it can be combined with
infrared measurements to obtain unified picture of electrodynamic properties of
cuprate superconductors.
