Title: Coherent organization of electronic correlations as a mechanism to enhance and stabilize high-T C cuprate superconductivity

Abstract

Strong diffusive or incoherent electronic correlations are the signature of the strange-metal normal state of the cuprate superconductors, with these correlations considered to be undressed or removed in the superconducting state. A critical question is if these correlations are responsible for the high-temperature superconductivity. Here, utilizing a development in the analysis of angle-resolved photoemission data, we show that the strange-metal correlations don’t simply disappear in the superconducting state, but are instead converted into a strongly renormalized coherent state, with stronger normal state correlations leading to stronger superconducting state renormalization. This conversion begins well above T C at the onset of superconducting fluctuations and it greatly increases the number of states that can pair. Therefore, there is positive feedback––the superconductive pairing creates the conversion that in turn strengthens the pairing. Although such positive feedback should enhance a conventional pairing mechanism, it could potentially also sustain an electronic pairing mechanism.

Fig. 1 Fig. 1 : Temperature-dependent ARPES spectra and self-energies. a–f Measured spectra from a mid-zone cut (s) of the antibonding band at multiple temperatures. g–l 2D fits to the corresponding ARPES spectra, with the main unknown parameters the superconducting gaps, the electronic self-energies and the bare electron band, where the dottedmore » curve is the bare-band dispersion from the fitting. m–r Correspondent self-energies extracted from the fit spectra on the left. t Imaginary part of the self-energy Σ″ (or scattering rate) vs. frequency and temperature obtained from the 2D fits. There is a strong reduction or gapping of the near EF scattering rate as temperature is lowered into the paired state, along with a shift of this scattering to high energies beyond the dashed line. Along with this is a strong kink or mass enhancement in the real part of self-energy Σ′ (u). These effects of Σ″ and Σ′ are responsible for the dramatic flattening and sharpening of the low-energy states of a–f, g–l. All data were taken with 9 eV photons, and the Fermi surface angle was θ = 22.5 degree« less
