The quantum statistics obeyed by integer-spin particles (bosons) in which any number of particles may occupy a given state. Bose-Einstein statistics describe physical systems in which the particle number is nonconservative, particles are indistinguishable, and cells of phase space are statistically independent. Such systems allow two polarization states, and exhibit totally symmetric wavefunctions. In 1940, Pauli Eric Weisstein's World of Biography showed that Bose-Einstein statistics follows from quantum field theory.
