A Fermi gas is an idealized model, an ensemble of many non-interacting fermions. Fermions are particles that obey Fermi–Dirac statistics, like electrons, protons, and neutrons, and, in …

We define the function f(ϵ) ≡ 1 eϵ / kBT + 1 , known as the Fermi distribution. In the T → ∞ limit, f(ϵ) → 1 2 for all finite values of ε. As T → 0, f(ϵ) approaches a step function Θ(− ϵ). The …

Ideal Fermi gas The properties of an ideal Fermi gas are strongly determined by the Pauli principle. We shall consider the limit: kBT µ, βµ 1 , which defines the degenerate Fermi gas. …

2017年2月1日 · Each single-particle orbit in the Fermi gasmodel is characterized by the momentum p and spin-isospin quantum numbers. Any stationary state of the Fermi gas is …

The special nature of the Fermi surface, which can be called ‘fragility’, plays an important role in the orthogonality theorem and the theory of superconductivity.

Fermi gas consists in the role played by correlations. A Fermi gas applies if the interaction can be accounted for at a mean-field level. One speaks of a Fermi liquid if the two-body short-range …
