Formula: Bose distribution function

Probability

Unit
The occupation probability indicates with which probability \(P\) a state with energy \( W \) at temperature \( T \) is occupied by a boson (for example a photon or phonon).

Energy

Unit
Energy state which can be occupied by a boson, for example by a photon or \(^4\text{He}\) atom.

Chemical potential

Unit
Chemical potential indicates the change of internal energy when the particle number of the boson gas changes. At \(T = 0 \) the chemical potential corresponds to the Fermi energy.

Temperature

Unit
Absolute temperature of the boson gas (for example a photon gas).

Boltzmann constant

Unit
Boltzmann constant is a natural constant, which appears more often in statistical physics and thermodynamics. It has the value: \( k_{\text B} = 1.380 \, 649 \, \cdot\, 10^{-23} \, \frac{\text J}{\text K} \).
