Bose gas facts for kids
Bose gas is a concept in quantum mechanics.
Classical mechanics has a concept called ideal gas. This concept describes how a gas usually behaves, in different settings. A bose gas is the analogous concept in quantum mechanics.
A bose gas is made of bosons with a positive spin value. These bosons also follow the BoseEinstein statistics. The statistical mechanics of bosons were developed by Satyendra Nath Bose for photons. Albert Einstein extended the theory, when he realized that an ideal gas of bosons would form a condensate at a low enough temperature. This condensate is known as a Bose–Einstein condensate. This is not the case with a classical ideal gas.

Figure 1: Various Bose gas parameters as a function of normalized temperature τ. The value of α is 3/2. Solid lines are for N=10,000, dotted lines are for N=1000. Black lines are the fraction of excited particles, blue are the fraction of condensed particles. The negative of the chemical potential μ is shown in red, and green lines are the values of z. It has been assumed that k =εc=1.
