Aspects of Non-Fermi-Liquid Metals


Pivovarov, Evgueny (Eugene) (2002) Aspects of Non-Fermi-Liquid Metals. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/20WA-FT36.


We consider several examples of metallic systems that exhibit non-Fermi-liquid behavior. In these examples the system is not a Fermi liquid due to the presence of a "hidden" order. The primary models are density waves with an odd-frequency-dependent order parameter and density waves with d-wave symmetry. In the first model, the same-time correlation functions vanish and there is a conventional Fermi surface. In the second model, the gap vanishes at the nodes. We derive the phase diagrams and study the thermodynamic and kinetic properties. We also consider the effects of competing orders on the phase diagram when the underlying microscopic interaction has a high symmetry.
