WebJan 23, 2024 · Despite its apparent simplicity, the Fermi-liquid (FL) theory is one of the most non-trivial theories of interacting fermions [1, 5–11]. In general terms, it states that a system of interacting fermions in dimension D > 1 displays behavior which differs from that of free fermions quantitatively rather than qualitatively. WebOct 8, 1992 · Effective Field Theory and the Fermi Surface. This is an introduction to the method of effective field theory. As an application, I derive the effective field theory of low energy excitations in a conductor, the Landau theory of Fermi liquids, and explain why the high- superconductors must be described by a different effective field theory.
