A central debate in the field of high-temperature superconductivity – the ability to conduct electricity without resistance at record high temperatures – is the nature of the underlying normal state. Is this a fluid of independent electrons with renormalized mass and velocity, as the 'Fermi liquid quasiparticles' that give rise to conventional low-temperature superconductivity? Or is instead a property emerging from the unconventional many-body physics of strongly correlated electrons? I will discuss this question, in the context of the copper oxides high-temperature superconductors, showing how we can use modern angle-resolved photoemission spectroscopy and a novel approach to control the number of electrons at the surface of these materials to probe electronic correlations, and whether these can wipe quasiparticles completely out of existence.
