Multichannel Kondo approach to the cuprate and recent laser ARPES data

The existing theoretical approaches have been unable to confront the large corpus of outstanding data on the cuprate superconductor in a persuasive and unified manner. There is a general opinion now growing that these theories miss some essential points. We propose one based on multichannel Kondo effect that is physically justifiable and confronts the data adequately. In addition to earlier data، the definitive proof of involvement of this effect has been now provided by the numerical agreement of the characteristic Kondo temperatures with the fluctuation frequencies at which Eliashberg function peaks. It is، therefore، suggested that the theory of multichannel Kondo effect be accepted as the correct theory of underdoped cuprate.
