Title: “Marginal Fermi Liquids from Singular Fermi Surfaces”

 

Abstract:

 

The Marginal Fermi Liquid (MFL) paradigm was designed to  reproduce the strange metal behaviour of the high Tc Cuprate compounds. However, to date there is no well defined theory which can reproduce MFL  behavior. As such it has not been possible to make (even) qualitiative predictions in any well defined fashion. In this talk I will show one can utilize recent ideas in high energy scattering to derive an effective field theory of Fermi surfaces with Von Hove singularities that reproduces MFL behavior. I will then use this theory to make predictions for such compounds and compare and contrast the results with the characteristics of high Tc superconductors.
