New physics of metals: fermi surfaces without Fermi liquids
1Joseph Henry Laboratories of Physics, Princeton University, Princeton, NJ 08554, USA.
Abstract:
I relate the historic successes, and present difficulties, of the renormalized quasiparticle theory of metals ("AGD" or Fermi liquid theory). I then describe the best-understood example of a non-Fermi liquid, the normal metallic state of the cuprate superconductors.
