论文摘要
预计加速光电探测器将在电磁真空中看到光子。但是，所需的极端加速已阻止了该量子真空效应的直接实验验证。在这项工作中，我们考虑了许多在电磁腔内包含的加速光电探测器。我们表明，可以集体增强来自空腔真空的产生的光子产生，例如可测量。合并的腔体射频电视系统映射到参数驱动的dicke型模型；当检测器数超过一定的临界值时，真空光子产生从正常相转变为增强的类似超级的倒置激光阶段。这样的模型可以实现为机械膜，在超导微波腔中经历了吉赫赫氏弯曲运动的光学活性缺陷浓度很高。我们提供的估计表明，最近相关的实验设备即将证明这种倒置的真空光子激光阶段。
An accelerating photodetector is predicted to see photons in the electromagnetic vacuum. However, the extreme accelerations required have prevented the direct experimental verification of this quantum vacuum effect. In this work, we consider many accelerating photodetectors that are contained within an electromagnetic cavity. We show that the resulting photon production from the cavity vacuum can be collectively enhanced such as to be measurable. The combined cavity-photodetectors system maps onto a parametrically driven Dicke-type model; when the detector number exceeds a certain critical value, the vacuum photon production undergoes a phase transition from a normal phase to an enhanced superradiant-like, inverted lasing phase. Such a model may be realized as a mechanical membrane with a dense concentration of optically active defects undergoing gigahertz flexural motion within a superconducting microwave cavity. We provide estimates suggesting that recent related experimental devices are close to demonstrating this inverted, vacuum photon lasing phase.
