Examining Spin Fluctuations Pairing Model From Angle Resolved Photoemission Spectra

ORAL

Abstract

The mechanism of superconductivity is a long standing puzzle in the cuprates. Among various proposed models, pairing through the exchange of spin fluctuations is one of the leading candidates. Here we use spectral functions measured from angle resolved photoemission spectroscopy to calculate this pairing interaction within a random phase approximation, and then determine whether for a reasonable choice of the Hubbard parameter `$U$', we obtain a reasonable $T_c$.
