DESCRIPTION:Prof. Andrea Damascelli\, University of British Columbia\, Van
 couver\, CA.\nA central debate in the field of high-temperature supercondu
 ctivity – the ability to conduct electricity without resistance at recor
 d high temperatures – is the nature of the underlying normal state. Is t
 his a fluid of independent electrons with renormalized mass and velocity\,
  as the 'Fermi liquid quasiparticles' that give rise to conventional low-t
 emperature superconductivity? Or is instead a property emerging from the u
 nconventional many-body physics of strongly correlated electrons? I will d
 iscuss this question\, in the context of the copper oxides high-temperatur
 e superconductors\, showing how we can use modern angle-resolved photoemis
 sion spectroscopy and a novel approach to control the number of electrons 
 at the surface of these materials to probe electronic correlations\, and w
 hether these can wipe quasiparticles completely out of existence.
