**bosonic** — adjective see boson … New Collegiate Dictionary

**Bosonic string theory** — is the original version of string theory, developed in the late 1960s. Although it has many attractive features, it has a pair of features that render it unattractive as a physical model. Firstly it predicts only the existence of bosons whereas… … Wikipedia

**Bosonic field** — In quantum field theory, a bosonic field is a quantum field whose quanta are bosons; that is, they obey Bose Einstein statistics. Bosonic fields obey canonical commutation relations, as distinct from the canonical anticommutation relations obeyed … Wikipedia

**String theory** — This article is about the branch of theoretical physics. For other uses, see String theory (disambiguation). String theory … Wikipedia

**Supersymmetric quantum mechanics** — In theoretical physics, supersymmetric quantum mechanics is an area of research where mathematical concepts from high energy physics are applied to the seemingly more prosaic field of quantum mechanics. IntroductionUnderstanding the consequences… … Wikipedia

**Bose–Einstein condensate** — A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (val|0|u=K, val| 273.15|u=°C, or val| 459.67|u=°F ). Under such supercooled conditions, a… … Wikipedia

**Fermion** — In particle physics, fermions are particles which obey Fermi Dirac statistics; they are named after Enrico Fermi. In contrast to bosons, which have Bose Einstein statistics, only one fermion can occupy a quantum state at a given time; this is the … Wikipedia

**Quantum field theory** — In quantum field theory (QFT) the forces between particles are mediated by other particles. For instance, the electromagnetic force between two electrons is caused by an exchange of photons. But quantum field theory applies to all fundamental… … Wikipedia

**Superspace** — has had two meanings in physics. The word was first used by John Wheeler to describe the configuration space of general relativity; for example, this usage may be seen in his famous 1973 textbook Gravitation .The second meaning refers to the… … Wikipedia

**Normal order** — For other uses, see Normal order (disambiguation). In quantum field theory a product of quantum fields, or equivalently their creation and annihilation operators, is usually said to be normal ordered (also called Wick order) when all creation… … Wikipedia
