WebApr 26, 2004 · Fermi Liquid Theory: Principles Landau developed the idea of quasiparticle excitations in the context of interacting Fermi systems. His theory is known as Fermi liquid theory. He introduced the idea phenomenologically, and later Abrikosov and Kalatnikov gave a formal derivation using diagrammatic perturbation theory to all orders. WebJun 14, 2024 · In 1956, physicist Lev Landau developed a theory describing the low-temperature properties of helium-3 as those of a liquid of interacting fermions. Landau’s Fermi-liquid theory turned out to be widely applicable. It successfully describes, for instance, the low-temperature properties of most metals.

WebThe basic idea of the Landau Fermi Liquid theory is to consider the excitations of the strongly interacting system instead of concentrating on the nature of the ground state. The scattering rate of the fermions is considerably reduced due to the Pauli exclusion principle. Webthe non-interacting Fermi liquid, and the renormalized Landau Fermi liquid (Pines & Nozieres).
