Using a … WebMay 27, 2024 · In particle physics, a boson is a type of particle that obeys the rules of Bose-Einstein statistics. These bosons also have a quantum spin with contains an integer value, such as 0, 1, -1, -2, 2, etc. (By comparison, there are other types of particles, called fermions, that have a half-integer spin, such as 1/2, -1/2, -3/2, and so on.)

We will explore the transition to Bose-Einstein condensation (BEC) of noninteracting bosons.
WebMay 2, 2016 · Of these, 0 and 4 are essentially bosonic in character (because 0 is the trivial phase in any case, and 4 is characterized by the presence of a Kramers doublet on the boundary, which can equally well occur in a bosonic system.) The rest are truly fermionic phases which have no analog in bosonic systems.
All observed elementary particles are either bosons (with integer spin) or fermions (with odd half-integer spin).
