论文摘要
我们研究了阳性k- essence标量场理论中的半古典沟通，并在滚动背景下传播超光照模式。由于这些理论的非线性性质而引起的自我互动对超光电信息传递率构成了限制。我们在概念模型中得出了一个新颖的比特率，限制在级别沟通中，一般的K效率理论自然会降低。我们的结果意味着，即使这些积极竞争性的K效率理论可能没有最大信息传播速度，但信息传输速率仍存在上限。
We study semi-classical communication in positivity-violating k-essence scalar field theories, with superluminal modes propagating on a rolling background. The self-interactions due to the non-linear nature of these theories pose a constraint on the rate of superluminal information transfer. We derive a novel bit rate bound on superluminal communication within a conceptual model, to which a general class of k-essence theories naturally reduces. Our result implies the possibility that, even if these positivity-violating k-essence theories may not possess a maximal information propagation speed, there is nevertheless an upper bound on the rate of information transfer.
