PlanetPhysics/Fermi Dirac Distribution

The Fermi-Dirac distribution gives the probability of a [[../Fermion/|fermion]] occupying a [[../StatisticalEntropy/|Microstate]] with [[../CosmologicalConstant/|energy]] $ϵ$ and [[../LebesgueMeasure/|chemical potential]] $\mu$ at a [[../BoltzmannConstant/|temperature]] T. It is:

$f(ϵ)=\frac{1}{1+exp(\frac{ϵ-\mu }{kT})}$
