相对论与量子物理

de Sitter Relativity and Quantum Physics

R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor, J. G. Pereira

摘要:

在存在宇宙学常数的情况下,被解释为一个纯粹的几何实体,物质的不存在由德西特时空表示。因此,普通的庞加莱狭义相对论不再有效,必须由德西特狭义相对论取代。通过考虑德西特时空中无自旋粒子的运动学,我们研究了这个时空的测地线,随后的正则动量的定义,并探索了可能的量子力学的含义。

英文摘要:

In the presence of a cosmological constant, interpreted as a purely geometric entity, absence of matter is represented by a de Sitter spacetime. As a consequence, ordinary Poincare' special relativity is no longer valid and must be replaced by a de Sitter special relativity. By considering the kinematics of a spinless particle in a de Sitter spacetime, we study the geodesics of this spacetime, the ensuing definitions of canonical momenta, and explore possible implications for quantum mechanics.
