Abstract

This work focuses on the theoretical investigation of the possible enhancement of superconductivity for the superconducting lead (Pb) by intensified gravitational interaction (IGI) between electron pairs. By applying the quantization theory of gravity (QTG), we obtained expressions for the enhanced superconducting transition temperature (), and superconducting energy gap (). By using the experimental, theoretical values and some plausible approximations of the parameters in the obtained expressions, the phase diagrams of superconducting energy gap versus temperature for lead at  and the enhanced superconducting energy gap versus temperature for lead at are plotted. By combining the two phase diagrams, we had shown the possible enhancement of the superconducting transition temperature from to and its superconducting energy gap fromto  for the superconducting lead.
