In a hot cloud (left panel) the cell size λ is small and the gas behaves classically. In a sufficiently cold gas (right panel) the effect of the Pauli exclusion principle becomes pronounced. The reduced density fluctuations can be quantified by counting atoms in different regions of the cloud (indicated in blue).
