bose_einstein

sisl.physics.bose_einstein(E, kT=0.1, mu=0.0)

Bose-Einstein distribution function

$$n_B(E,k_{B}T,\mu )=\frac{1}{\exp [\frac{E-\mu }{k_{B}T}]-1}$$

Parameters:

• E (ArrayLike) – energy evaluation points

• kT (float) – temperature broadening

• mu (float | ArrayLike) – chemical potential

Returns:

the Bose-Einstein distribution, same length as E

Return type:

numpy.ndarray
