= Bose–Einstein correlations
{wiki=Bose–Einstein_correlations}
Bose-Einstein correlations refer to a statistical phenomenon that arises in quantum mechanics, specifically in the context of indistinguishable particles that follow Bose-Einstein statistics. These particles, known as bosons, include examples like photons (light particles) and helium-4 atoms. The essential aspect of Bose-Einstein statistics is that, unlike fermions (which follow the Pauli exclusion principle and cannot occupy the same quantum state), bosons can occupy the same quantum state.
