最小长度与Unruh效应

A minimal length versus the Unruh effect

Piero Nicolini, Massimiliano Rinaldi

摘要:

在这封信中,我们研究的辐射测量的加速探测器,耦合到一个标量场,在存在一个基本的最小长度。后者是通过修改动量空间格林函数来实现的。在对探测器进行标定后,我们发现场量子的净通量可以忽略不计,并且没有普朗克谱。我们讨论了可能的解释,这一结果,我们评论的实验影响重离子碰撞和原子系统。

英文摘要:

In this Letter we study the radiation measured by an accelerated detector, coupled to a scalar field, in the presence of a fundamental minimal length. The latter is implemented by means of a modified momentum space Green's function. After calibrating the detector, we find that the net flux of field quanta is negligible, and that there is no Planckian spectrum. We discuss possible interpretations of this result, and we comment on experimental implications in heavy ion collisions and atomic systems.
