The chemical potential (16b), scaled with as function of the dimensionless temperature , with , for the number of particles , , , , and . Note that the results with 32 particles (double dashed-dotted line) are close to the grand canonical ensemble result (black line in long dashes) computed from (3). A comparison with the Sommerfeld approximation for low temperatures is shown in the inset.
