ABSTRACT
Let us consider a noninteracting Fermi gas in equilibrium at a temperature T. The probability that a single particle has energy ϵ is given by the well-known expression f ( ϵ ) = 1 1 + exp [ ( ϵ − μ ) / k T ] https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429495717/2cc6e3e4-f702-48c8-b407-59783ef3d6a6/content/eq1.tif"/>
