Bose-Einstein statistics

In statistical mechanics, Bose-Einstein statistics means the statistics of a system where you can not tell the difference between any of the particles, and the particles are bosons. Bosons are fundamental particles like the photon.

The Bose-Einstein distribution tells you how many particles have a certain energy. The formula is

${\displaystyle n(\varepsilon )={\frac {1}{e^{(\varepsilon -\mu )/kT}-1}}}$

with ${\displaystyle \varepsilon >\mu }$ and where:

n(ε)  is the number of particles which have energy ε

ε  is the energy

μ is the chemical potential

k is Boltzmann's constant

T is the temperature

If ${\displaystyle \varepsilon -\mu \gg kT}$, then the Maxwell–Boltzmann statistics is a good approximation.
