Fermi Gas

Model of non-interacting fermions — the stuff of metals, neutron stars, white dwarfs, and ultracold Fermi gases.

Specifications & Metrics

An ideal Fermi gas is a physical model assuming a collection of non-interacting fermions in a constant potential well.
Fermions have half-integer spin and follow Fermi–Dirac statistics; the integer-spin counterpart is the Bose gas.
Key examples include charge carriers in a metal, nucleons in a nucleus, neutrons in a neutron star, and electrons in a white dwarf.
