We examine some of the issues concerning the validity of Fermi liquid theory in two dimensions. Contrary to previous claims, we find that the quasiparticle residue is nonzero and that the quasiparticle interaction function in the forwardscattering case is nondivergent for all values of the repulsive
The Landau theory of Fermi liquids is reformulated by taking the thermodynamic potential, rather than the energy density, as the primary concept. This leads to a new definition of the quasiparticle interaction function which can be identified with the physical forward scattering amplitude of two qua
We propose a microscopic justification for the recently proposed "marginal Fermi-liquid" (MFL) phenomenology of the high Te materials. In some models, and for sufficiently strong interactions, excitonic charge and spin modes between quasi-coherent one-particle states at the chemical potential and hi
