标题： Low Energy Lorentz Violation in Polymer Quantization Revisited

摘要： 在以前的工作中，已经表明聚合物量子化标量场理论预测，即使是一个惯性观察者也可以经历自发激发。 这一预测在低能情况下被证明是成立的。 然而，在这些论文中假设了聚合物尺度是常数。 但可以放松这个条件，得到一个更大的理论类，其中聚合物尺度是动量的函数。 低能洛伦兹破坏的预测是否适用于所有这些理论？ 在本文中，我们证明了这一点。 我们还得到了其中一些理论的辐射率的修改结果。 显示英文摘要

摘要： In previous work, it had been shown that polymer quantized scalar field theory predicts that even an inertial observer can experience spontaneous excitations. This prediction was shown to hold at low energies. However, in these papers it was assumed that the polymer scale is constant. But it is possible to relax this condition and obtain a larger class of theories where the polymer scale is a function of momentum. Does the prediction of low energy Lorentz violation hold for all of these theories? In this paper we prove that it does. We also obtain the modified rates of radiation for some of these theories.
