非常狭义相对论中的非对易时空

Noncommutative Spacetime in Very Special Relativity

Sudipta Das, Subir Ghosh, Salvatore Mignemi

摘要:

Cohen和Mr.how [1]提出的非常狭义相对论(VSR)框架证明了Poincaré群的一个真子群(特别是ISIM(2))足以描述迄今观测到的物理现象的时空对称性。随后,Gibbons、Gomis和Pope [2]提出了后者的变形$DISIM_b(2)$。在目前的工作中,我们介绍了一种新的非交换(NC)时空结构,潜在的$DISIM_b(2)$。这使我们能够明确地构建$DISIM_b(2)$生成器,由洛伦兹旋转生成器和平移生成器组成。利用Darboux映射技术,我们构造了一个点粒子拉格朗日量,它存在于我们提出的NC相空间中,并且满足Gibbons等人提出的修正色散关系。等[2]。有趣的是,在我们的公式中,动量代数变成了非对易的。

英文摘要:

Very Special Relativity (VSR) framework, proposed by Cohen and Glashow [1], demonstrated that a proper subgroup of the Poincaré group, (in particular ISIM(2)), is sufficient to describe the spacetime symmetries of the so far observed physical phenomena. Subsequently a deformation of the latter, $DISIM_b(2)$, was suggested by Gibbons, Gomis and Pope [2]. In the present work, we introduce a novel Non-Commutative (NC) spacetime structure, underlying the $DISIM_b(2)$. This allows us to construct explicitly the $DISIM_b(2)$ generators, consisting of a sector of Lorentz rotation generators and the translation generators. Exploiting the Darboux map technique, we construct a point particle Lagrangian that lives in the NC phase space proposed by us and satisfies the modified dispersion relation proposed by Gibbons et. al. [2]. It is interesting to note that in our formulation the momentum algebra becomes non-commutative.
