Proposal to determine the spectrum of pairing glue in high-temperature superconductors
A method which extracts the spectrum of the pairing function from the ARPES measurements in high temperature superconductors which makes a minimum of theoretical assumptions, does not use any prejudicial form of the pairing fluctuation spectrum as an input, and contains a self-consistency test was proposed. In contrast to the analysis of optical conductivity, the approach uses single particle spectra which contains more information and explicitly gives the evolution of the pairing spectrum with temperature in the superconducting state. Implementation of this approach through appropriate experiment promises to yield the answer to one of the central questions in the high Tc problem.
