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 …

The Sommerfeld expansion provides a systematic way of expanding these expressions in powers of \(T\) and is an important analytical tool in analyzing the low temperature properties of 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. …

We discuss basic properties of a gas of fermions at low temperature. We shall get some intuition about what the particles are doing by examining the Fermi-Dirac distribution function. We shall …

Some terminology: “Fermi gas” refers to a noninteracting or weakly-interacting gas of Fermions, which at low temperatures will exhibit a Fermi surface due to Pauli exclusion.

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 Systems 8.1 The Perfect Fermi Gas In this chapter, we study a gas of non-interacting, elementary Fermi par-ticles. Since the particles are non-interacting, the potential energy is …

Explains free fermions, properties, specific heat, white dwarf and neutron star, bond theory, diodes, non-viscous hydrodynamics, diffusion, continuity equation with diffusion, heat …

Why is it that particles with half-integer spin are Fermi particles whereas particles with integer spin are Bose particles? An explanation has been worked out by Pauli from complicated arguments …

The Fermi energy is a concept in quantum mechanics usually referring to the energy difference between the highest and lowest occupied single-particle states in a quantum system of non …
