Kappa-Minkowski时空:数学形式及其在普朗克尺度物理中的应用

Kappa-Minkowski spacetime: mathematical formalism and applications in Planck scale physics

Anna Pachoł

摘要:

本文提出了应用非对易时空描述,特别是卡帕变形闵可夫斯基时空和德林费尔德变形理论作为双狭义相对论(DSR)的数学形式的可能性,DSR被认为是量子引力理论的唯象极限。变形的相对论对称性描述的Hopf代数语言。在(量子)卡帕-闵可夫斯基时空的情况下,对称群由(量子)卡帕-庞加莱霍普夫代数描述。变形的相对论对称性被用来构造DSR代数,它将非交换坐标与对称代数的生成元统一起来。它包含变形的Heisenberg-Weyl子代数。证明了DSR代数可以由未变形代数通过生成元的非线性变换得到。我们表明,在普朗克尺度物理的应用的可能性与量子时空的某些实现,这反过来又导致变形色散关系。

英文摘要:

The dissertation presents possibilities of applying noncommutative spacetimes description, particularly kappa-deformed Minkowski spacetime and Drinfeld's deformation theory, as a mathematical formalism for Doubly Special Relativity theories (DSR), which are thought as phenomenological limit of quantum gravity theory. Deformed relativistic symmetries are described within Hopf algebra language. In the case of (quantum) kappa-Minkowski spacetime the symmetry group is described by the (quantum) kappa-Poincare Hopf algebra. Deformed relativistic symmetries were used to construct the DSR algebra, which unifies noncommutative coordinates with generators of the symmetry algebra. It contains the deformed Heisenberg-Weyl subalgebra. It was proved that DSR algebra can be obtained by nonlinear change of generators from undeformed algebra. We show that the possibility of applications in Planck scale physics is connected with certain realizations of quantum spacetime, which in turn leads to deformed dispersion relations.
