Query: Hybridized quadrupole-dipole exciton effects in $Cu_2O$ - Organic
  Heterostructure   In the present work we discuss resonant hybridization of the $1S$ quadrupole
Wannier-Mott exciton (WE) in a $Cu_2O$ quantum well with the Frenkel (FE)
dipole exciton in an adjacent layer of organic DCM2:CA:PA. The coupling between
excitons is due to interaction between the gradient of electric field induced
by DCM2 Frenkel exciton and the quadrupole moment of the $1S$ transition in the
cuprous oxide. The specific choice of the organic allows us to use the
mechanism of 'solid state solvation' to dynamically tune the WE and FE into
resonance during time $\approx 3.3 \: ns$ (comparable with the big life time of
the WE) of the 'slow' phase of the solvation. The quadrupole-dipole hybrid
utilizes the big oscillator strength of the FE along with the big lifetime of
the quadrupole exciton, unlike dipole-dipole hybrid exciton which utilizes big
oscillator strength of the FE and big radius of the dipole allowed WE. Due to
strong spatial dispersion and big mass of the quadrupole WE the hybridization
is not masked by the kinetic energy or the radiative broadening. The lower
branch of the hybrid dispersion exhibits a pronounced minimum and may be used
in applications. Also we investigate and report noticeable change in the
coupling due to a induced 'Stark effect' from the strong local electric field
of the FE. We investigated the fine energy structure of the quantum well
confined ortho and para excitons in cuprous oxide.
