Quantum Mechanics Dictionary
Definition
A quantum mechanics concept defining a model element, mathematical object, or experimental method used to predict measurable outcomes. It applies when required assumptions and definitions are specified and yields computable probabilities and expectation values. It does not ensure correctness without validation of approximations, numerical stability, and consistency of units and conventions.

Definition
The equilibrium occupancy probability for fermionic single-particle states at temperature T and chemical potential μ, given by f(E) = 1 / (exp((E − μ)/kT) + 1), reflecting the Pauli exclusion principle.
