The antisymmetric exchange statistics of identical fermions. Interchanging two one-particle labels reverses the total state, and fermionic creation operators anticommute. Occupation of a one-particle mode is therefore zero or one, giving the Pauli exclusion principle; thermal equilibrium leads to the Fermi-Dirac distribution. Color, flavor, spin and orbital factors must together have the required antisymmetry, even if one factor is symmetric.

Fermi–Dirac statistics is a quantum statistical framework that describes the distribution of particles, specifically fermions, which are particles that obey the Pauli exclusion principle. Fermions include particles like electrons, protons, and neutrons, and they have half-integer spin (e.g., 1/2, 3/2). In systems of indistinguishable fermions, no two particles can occupy the same quantum state simultaneously.
