具有扭曲对称性的非对易空间的二次量子化

On second quantization on noncommutative spaces with twisted symmetries

Gaetano Fiore

摘要:

通过应用一般的扭曲诱导的恒星变形过程,我们翻译的二次量子化的玻色子/费米子系统的对称时空中的非交换语言。该程序变形协调的方式时空代数及其对称性,波力学描述的一个系统的n玻色子/费米子,代数的创建和湮灭运营商,以及后者的交换关系与功能的时空;我们的关键要求是模式分解的量子场的独立性。在保守的观点中,非对易坐标的使用可以被看作是一种更好地表达特殊类型的非定域相互作用的方法。在非保守情形下,我们得到了一个与量子力学公理和玻色-费米统计相一致的非对易时空上的QFT协变框架。一个显著的特征是场对易关系仍然是“场(反)对易者=分布”的类型。以Moyal空间(时间)上的非相对论性和自由相对论性相互作用QFT为例,说明了所得结果。

英文摘要:

By application of the general twist-induced star-deformation procedure we translate second quantization of a system of bosons/fermions on a symmetric spacetime in a non-commutative language. The procedure deforms in a coordinated way the spacetime algebra and its symmetries, the wave-mechanical description of a system of n bosons/fermions, the algebra of creation and annihilation operators and also the commutation relations of the latter with functions of spacetime; our key requirement is the mode-decomposition independence of the quantum field. In a conservative view, the use of noncommutative coordinates can be seen just as a way to better express non-local interactions of a special kind. In a non-conservative one, we obtain a covariant framework for QFT on the corresponding noncommutative spacetime consistent with quantum mechanical axioms and Bose-Fermi statistics. One distinguishing feature is that the field commutation relations remain of the type "field (anti)commutator=a distribution". We illustrate the results by choosing as examples interacting non-relativistic and free relativistic QFT on Moyal space(time)s.
