Fermi liquid
[′fer·mē ‚lik·wəd] (cryogenics)
A liquid of particles which have Fermi-Dirac statistics; an example is the liquid phase of helium-3, in which the atoms belong to the isotope with mass number 3.

These "charged fluid particles" reproduce charged spinless quasiparticles which determine the superfluidity component of Bose or Fermi liquid by action of the static magnetic field.
Further, we present a new model for description of charged Bose or Fermi liquid via a nonideal Bose gas consisting of charged sound particles.
His topics include the one-particle relativistic distribution function, curved space-time and cosmology, the density operator, applications to nuclear matter, and the relativistic Fermi liquid.
Following the expert commentaries, six chapters cover fluctuation and gauge effect on the behavior of superconductors, the exciton enhancement mechanism theory, spontaneously broken symmetry and inhomogeneous superconducting states in ferromagnet/superconductor nanostructures, superconductivity in chemical vapor-deposition diamond thick films, and a model of super conductivity in Fermi liquid.
At least one electron from each atom moves about independently, collectively forming a so-called Fermi liquid.
What is clear is that the 2 decades or more of efforts to fit all these phenomena into a Fermi liquid description are a catalog of failure," Anderson argues in the December 1995 Physics World, "and it is time we opened our minds to new ways of thinking.
As a theoretical physicist, Ashcroft could not really establish if metallic hydrogen at absolute zero 1) acted as a two component Fermi liquid, 2) behaved much like the unusual theoretical one-component plasma [54, 55], or 3) retained the essential characteristic of a Bravais lattice, an ordered proton field with fully degenerate electrons.
With enough pressure, hydrogen could then move from the two component Fermi liquid [36, 37,41,46-48, 70], to the crystalline solid [19], and finally into a zero-temperature structured liquid state [61].
2] Furthermore, it is known that superfluidity phenomena can also be observed in Fermi liquid [6].
The state of the material where these heavy fermions appear is sometimes called a Kondo lattice, sometimes a Fermi liquid.
Although they did not find direct evidence for the Fermi liquid state, in the case of heavy fermions based on uranium they did find evidence for such a narrow bandwidth even before the Fermi liquid state itself forms.
