Abstract
We show that the momentum-dependent scaling exponents of the holographic fermion self-energy of the conformal-to-AdS2 Gubser-Rocha model can describe new findings from angle-resolved photoemission spectroscopy experiments on a single-layer (Pb,Bi)2Sr2-xLaxCuO6+δ copper oxide. In particular, it was recently observed in high-precision measurements on constant energy cuts along the nodal direction that
