Query: Interplay between collective modes in hybrid electron gas-superconductor
  structures   We study hybridization of collective plasmon and
Carlson-Goldman-Artemenko-Volkov modes in a hybrid system, consisting of a
two-dimensional layers of electron gas in the normal state and superconductor,
coupled by long-range Coulomb forces. The interaction between these collective
modes is not possible in a regular single-layer two-dimensional system since
they exist in non-overlapping domains of dimensionless parameter $\omega\tau$,
where $\omega$ is the external electromagnetic field frequency and $\tau$ is
electron scattering time. Thus, in a single-layer structure, these modes are
mutually exclusive. However, the coupling may become possible in a hybrid
system consisting of two separated in space materials with different
properties, in particular, the electron scattering time. We investigate the
electromagnetic power absorption by the hybrid system and reveal the conditions
necessary for the hybridization of collective modes.
