Fermi–Dirac statistics is a type of quantum statistics that applies to the physics of a system consisting of many non-interacting, identical particles that obey the Pauli exclusion principle.

developed fundamental quantum mechanical statistical framework
Fermi independently derived this statistical method to describe the behavior of particles that obey the Pauli exclusion principle, which are now called fermions.
Fermi–Dirac statistics is a branch of quantum statistics that describes the behavior of systems composed of many identical, non-interacting particles. These particles, known as fermions, are defined by their adherence to the Pauli exclusion principle, which dictates that no two fermions can occupy the same quantum state simultaneously.

It provides the mathematical basis for the Fermi–Dirac distribution, which calculates the probability of particles occupying specific energy states. This statistical model is a cornerstone of statistical mechanics and is essential for understanding the physical properties of matter at the quantum level.
