Fer·mi-Di·rac statistics

 (fĕr′mē-dĭ-răk′)
n. (used with a sing. verb)
The statistics used in statistical mechanics to describe the behavior of large numbers of fermions.

[After Enrico Fermi and Paul Adrien Maurice Dirac, who developed the statistics.]

Fermi-Dirac statistics

n
(General Physics) physics the branch of quantum statistics used to calculate the permitted energy arrangements of the particles in a system in terms of the exclusion principle. Compare Bose-Einstein statistics

The method is based on an iterative and self-consistent solution of the charge neutrality equation with full Fermi-Dirac statistics for the carriers at finite temperature and on the use of statistical analyses to give analytic expressions that represent the calculated data sets.
Dirac (see 1930) also contributed, so that the result is known as the Fermi-Dirac statistics.
It gets its name because it proposes that for every particle known to the standard model there exists a supersymmetric partner that has the same properties but obeys the opposite of the two kinds of statistical law that apply to subatomic particles, Bose-Einstein statistics and Fermi-Dirac statistics.
We want to show that from this nonlinear model we may also derive the required statistics of photons and electrons that photons obey the Bose-Einstein statistics and electrons obey the Fermi-Dirac statistics.
What Alder calls the "really deep problem" is related to the feature of quantum mechanics known as Fermi-Dirac statistics.
