粒空间诱导的狭义相对论

Special Relativity induced by Granular Space

Petr Jizba, Fabio Scardigli

摘要:

我们表明,特殊的相对论动力学与量子力学和超统计的概念相结合时,可以被解释为产生于两个互锁的非相对论随机过程,在不同的能量尺度上运行。这种解释导致费曼振幅是在欧几里德制度相同的布朗粒子通过颗粒空间传播的转移概率。某种时空粒度可以被认为是在更大尺度上出现各种对称性的原因。为了说明,我们还考虑了无自旋相对论粒子的动力学和传播子。讨论了双狭义相对论、量子场论、量子引力和宇宙学的意义。

英文摘要:

We show that the special relativistic dynamics when combined with quantum mechanics and the concept of superstatistics can be interpreted as arising from two interlocked non-relativistic stochastic processes that operate at different energy scales. This interpretation leads to Feynman amplitudes that are in the Euclidean regime identical to transition probability of a Brownian particle propagating through a granular space. Some kind of spacetime granularity could be held responsible for the emergence at larger scales of various symmetries. For illustration we consider also the dynamics and the propagator of a spinless relativistic particle. Implications for doubly special relativity, quantum field theory, quantum gravity and cosmology are discussed.
