Physics:Quantum particles/boson
boson is a Book II topic in the Quantum Collection. A boson is a particle that follows Bose–Einstein statistics and can occupy the same quantum state as other identical particles. Bosons are responsible for mediating interactions and can also form collective quantum states. Bosons have symmetric many-particle wavefunctions, so identical bosons can occupy the same quantum state. This exchange behavior underlies photons in a laser, phonons in a crystal, superfluid helium, and Bose-Einstein condensates. Gauge bosons mediate fundamental interactions, while composite bosons can emerge from pairs or bound states of fermions.
Description
Bosons differ from fermions in that they are not subject to the Pauli exclusion principle. This allows many bosons to occupy the same quantum state, leading to phenomena such as coherent radiation and collective quantum behavior.
Some bosons act as carriers of fundamental interactions, while others arise as collective excitations in matter.
Properties
- can share the same quantum state
- not restricted by the exclusion principle
- include force carriers and collective excitations
