Single particle state distribution

Occupancy of a single-particle state of bosons is the probability of a single boson to occupy a state with a certain amount of energy. The occupancy depends on the energy of the state and the temperature and the chemical potential of the system.

Conditions:

  1. \(E_i > \mu\).
