Interference of superconducting and dielectric correlations in the IR spectra of high-temperature superconductors
Zhukovskii E. A. , Kopaev Yu. V.
Features caused in the IR spectra of a system with dielectric and superconducting correlations by the quasiparticle state density might be mistaken as implying a nonstandard temperature dependence of the gap and an upper biased value of 2Δ/
