Possibility of a high-Tc superconductivity based on "Coulomb" mechanisms for Cooper pairing of carriers
It is shown that Anderson's assertion that it is not possible to reach high superconducting transition temperatures Tc by means of nonphonon ("Coulomb") mechanisms for Cooper pairing is not correct in general. The reason is that local-field effects increase the charge of the quasiparticles. This increase compensates nearly completely for the decrease in the attraction between electrons due to the renormalization of the coupling constant Я by a factor of (1+Я). As a result, it is possible to reach values Tc> 100 K.
