Dynamical charge susceptibility in
superconducting cuprates.

• Mikhail Eremin
• Kazan State University, Russian Federation.
• The density-density response function is closely
  related to the optical conductivity in ab plane
  and therefore can be tested experimentally. Most
  interestingly a feedback of a superconductivity
  has been observed by the means of the optical
  conductivity in hole-doped Basov et al. at
  energy 1000cm-1 (Tc 93 K) and in the
  electron-doped at 100cm-1 Pimenov et al. (Tc
  25 K ).
