论文摘要
由于量子流体，可以在实验室中研究田间对弯曲空间的量子效应。在这里，我们使用北极流体来研究鹰效应，这将来自声学范围的量子真空的发射相关。我们展示了非平衡物理学如何影响分散关系，因此相关波的发射和传播：地平线两侧的流体特性对于观察鹰效应至关重要。我们发现，可以通过在光学双重性方面支持地平线上游流体的相位和密度来优化发射。这为观察到平衡系统中的鹰效应的新途径以及研究弯曲空间上的田野新现象学的研究。
Quantum effects of fields on curved spacetimes may be studied in the laboratory thanks to quantum fluids. Here we use a polariton fluid to study the Hawking effect, the correlated emission from the quantum vacuum at the acoustic horizon. We show how out-of-equilibrium physics affects the dispersion relation, and hence the emission and propagation of correlated waves: the fluid properties on either side of the horizon are critical to observing the Hawking effect. We find that emission may be optimised by supporting the phase and density of the fluid upstream of the horizon in a regime of optical bistability. This opens new avenues for the observation of the Hawking effect in out-of-equilibrium systems as well as for the study of new phenomenology of fields on curved spacetimes.
