声黑洞谱的稳健性
On the robustness of acoustic black hole spectra
摘要：
我们研究的鲁棒性的频谱发射的声学黑洞考虑一系列的稳态流，成为亚音速或超音速，即当地平线消失。我们研究了玻色-爱因斯坦凝聚体的超光速波哥留波夫色散。我们发现，直到视界消失，光谱仍然是显着的普朗克。当流动到处都是超音速时，新的成对产生通道打开。这将是一个即将到来的工作的主题。
英文摘要：
We study the robustness of the spectrum emitted by an acoustic black hole by considering series of stationary flows that become either subsonic or supersonic, i.e. when the horizon disappears. We work with the superluminal Bogoliubov dispersion of Bose--Einstein condensates. We find that the spectrum remains remarkably Planckian until the horizon disappears. When the flow is everywhere supersonic, new pair creation channels open. This will be the subject of a forthcoming work.
