论文摘要
弯曲的空间上的量子波动会导致量子真空的颗粒对发射，如黑洞的鹰效应。我们使用光学类似物来重力研究曲率对量子发射的影响。由于分散，时空曲率在这里随频率而变化。我们通过分析计算所有频率的粒子通量，相关性和纠缠。我们发现地平线会以特征性的光谱形状增加通量。光子数相关性从多模式转变，接近最大纠缠。量子状态是量子场理论实验室测试的模式转换的诊断。
Quantum fluctuations on curved spacetimes cause the emission of pairs of particles from the quantum vacuum, as in the Hawking effect from black holes. We use an optical analogue to gravity to investigate the influence of the curvature on quantum emission. Due to dispersion, the spacetime curvature varies with frequency here. We analytically calculate for all frequencies the particle flux, correlations and entanglement. We find that horizons increase the flux with a characteristic spectral shape. The photon number correlations transition from multi- to two-mode, with close to maximal entanglement. The quantum state is a diagnostic for the mode conversion in laboratory tests of quantum field theory on curved spacetimes.
