Quantum Statistics¶
Quantum statistics is a description of multiple quantum particles in statistical mechanics. As opposed to Classical Statistics, particles of a particular type are indistinguishable from one another, i.e. exchanging two particles within an ensemble does lead to a new configuration.
An important concept that determines the existence of two quantum statistics is the Pauli exclusion principle. It states that two or more identical particles with half-integer spins (which are called fermions) cannot simultaneously occupy the same quantum state within a system that obeys the laws of quantum mechanics. This principle does not apply to quantum particles with whole-integrer spins (bosons).
