具有正规场算子的U(1)-不变场论

The U(1)-invariant field theories with normal field operators

Piotr Sniady, Marcin Zygmunt

摘要:

在本文中,我们考虑一个非常一般的U(1)-不变场论,使得一个场算子与它的伴随算子交换,这对应于一个带电玻色子理论。我们表明,从这样一个不变性遵循的粒子和反粒子的存在与相同的物理状态。场算符总是粒子产生算符和反粒子湮灭算符之和。我们详细研究的情况下,创建和湮灭运营商因式分解,并表明,这种运营商是密切相关的q-变形的对易关系。

英文摘要:

In this paper we consider a very general U(1)-invariant field theory such that a field operator commutes with its adjoint, what corresponds to a theory of a charged bosonic particle. We show that from such an invariance follows the existence of particles and antiparticles associated to the same physical state. The field operator always turns out to be a sum of a particle creation and an antiparticle annihilation operators. We study in detail the case when creation and annihilation operators factorize and show that such operators are closely related to q-deformed commutation relations.
