DSR作为宇宙结构的解释

DSR as an explanation of cosmological structure

Joao Magueijo

摘要:

变形狭义相对论(DSR)是光速变化(VSL)的可能实现之一。它使通常的二次色散关系变形,使光速变得依赖于能量,并通过假设洛伦兹群的非线性表示来避免首选框架。该理论可用于诱导一个变化的声速,能够产生(近)标度不变的密度波动,在最近的一封信中讨论。我们确定的洛伦兹群的非线性表示,导致标度不变性,找到一个普遍的结果。我们还研究了高阶场论,可以建立代表它。

英文摘要:

Deformed special relativity (DSR) is one of the possible realizations of a varying speed of light (VSL). It deforms the usual quadratic dispersion relations so that the speed of light becomes energy dependent, with preferred frames avoided by postulating a non-linear representation of the Lorentz group. The theory may be used to induce a varying speed of sound capable of generating (near) scale-invariant density fluctuations, as discussed in a recent Letter. We identify the non-linear representation of the Lorentz group that leads to scale-invariance, finding a universal result. We also examine the higher order field theory that could be set up to represent it.
