WebIf the Fermi liquid is isotropic (which we will assume further for simplicity), then the Fermi surface is spherical and both F kk 0and G kk depend only on the angle #between k and k0. In this model, the e ective mass m is constant along the Fermi surface. 3.4.2 Relation between e ective mass and interaction in the Galilean-invariant case http://eduardo.physics.illinois.edu/phys561/LL-11-17-09.pdf

WebJoaquin (Quin) Mazdak Luttinger (December 2, 1923 – April 6, 1997) was an American physicist well known for his contributions to the theory of interacting electrons in one-dimensional metals (the electrons in these metals are said to be in a Luttinger-liquid state) and the Fermi-liquid theory. He received his BS and PhD in physics from MIT in 1947. … Web• In the Landau theory of the Fermi liquid we considered the low energy states and we saw that they can be described in terms of particle- hole pairs. In dimensions D>1 the momentum δ~qof the pair is not necessarily parallel to the Fermi wave vector pFof the location of the 6.1.

Only three pages long, but good microscopic derivation of quasiparticle lifetime … Fermi liquid theory (also known as Landau's Fermi-liquid theory) is a theoretical model of interacting fermions that describes the normal state of most metals at sufficiently low temperatures. The interactions among the particles of the many-body system do not need to be small. The phenomenological … See more The key ideas behind Landau's theory are the notion of adiabaticity and the Pauli exclusion principle. Consider a non-interacting fermion system (a Fermi gas), and suppose we "turn on" the interaction slowly. Landau … See more The Fermi liquid is qualitatively analogous to the non-interacting Fermi gas, in the following sense: The system's dynamics and … See more The experimental observation of exotic phases in strongly correlated systems has triggered an enormous effort from the theoretical … See more • Classical fluid • Fermionic condensate • Luttinger liquid • Luttinger's theorem • Strongly correlated quantum spin liquid See more The following differences to the non-interacting Fermi gas arise: Energy The energy of a many-particle state is not simply a sum of the single-particle energies of all occupied states. Instead, the change in … See more The term non-Fermi liquid, also known as "strange metal", is used to describe a system which displays breakdown of Fermi-liquid behaviour.
