High-Tc Superconductors Are Very Kinky - Update 3

Another update of my compilation of papers on the nature of the "kink" in the band dispersion observed in ARPES measurement on high-Tc superconductors. This time it comes from a theoretical analysis with parameters extracted from the inelastic neutron scattering (INS) experiment and applied to the ARPES results[1].

What they found out was that the scattering mediated by the incommensurate spin excitation seen in the INS measurement could account for practically all of the ARPES observations on the YBCO compound. This includes the observation of the kinks and their temperature "evolution" (or non-evolution) with temperature across the doping range. The previous models that depended on the magnetic resonance that disappeared above Tc and strongly dependent on temperature is a red herring.

This paper has been accepted on Nature Physics. A complete citation to it will be added once it is published.
