色散关系对相对论多普勒频移法测量Unruh效应的影响

Influence of the dispersion relation on the Unruh effect according to the relativistic Doppler shift method

F. Hammad, A. Landry, D. Dijamco

摘要:

我们研究了色散关系对洛仑兹提升任意色散关系的闵可夫斯基真空涨落相位的Unruh效应的影响。我们发现,与无质量场所表现出的线性色散关系不同,一般色散关系会失去热性。我们发现,热出现不同的“表观”戴维斯-昂鲁温度取决于观察者的加速度和偏离色散关系的线性度。这种方法的优点是直观,能够精确地确定为什么会发生这种热损失,以及何时这种偏离热变得明显。我们讨论我们的结果与著名的热化定理和Rindler噪声的概念之间的根本区别的联系。我们研究了可能的实验验证我们的结果的基础上,一个成功的设置,用于测试的经典类似物的Unruh效应最近在文献中描述。

英文摘要:

We examine the influence of the dispersion relation on the Unruh effect by Lorentz boosting the phase of Minkowski vacuum fluctuations endowed with an arbitrary dispersion relation. We find that, unlike what happens with a linear dispersion relation exhibited by massless fields, thermality is lost for general dispersion relations. We show that thermality emerges with a varying "apparent" Davies-Unruh temperature depending on the acceleration of the observer and on the degree of departure from linearity of the dispersion relation. The approach has the advantage of being intuitive and able to pinpoint why such a loss of thermality occurs and when such a deviation from thermality becomes significant. We discuss the link of our results with the well-known fundamental difference between the thermalization theorem and the concept of Rindler noise. We examine the possible experimental validation of our results based on a successful setup for testing the classical analogue of the Unruh effect recently described in the literature.
