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.

The article has only treated the case in which particles have a parabolic relation between energy and momentum, as is the case in non-relativistic mechanics. For particles with energies close to their respective rest mass, the equations of special relativity are applicable. Where single-particle energy is given by: For this system, the Fermi energy is given by:
