Open AccessMomentum-dependent scaling exponents of nodal self-energies measured in strange metal cuprates and modelled using semi-holography
The anomalous strange metal phase found in high-Tc cuprates does not follow the conventional condensed-matter principles enshrined in the Fermi liquid and presents a great challenge for theory. Highly precise exp...
