离子环上声黑洞的霍金辐射

Hawking Radiation from an Acoustic Black Hole on an Ion Ring

Birger Horstmann, Benni Reznik, Serena Fagnocchi, J. Ignacio Cirac

摘要:

在这篇文章中,我们提出了模拟声学黑洞的离子环。如果离子以静止且不均匀的速度分布旋转,则可能出现离子速度超过声子群速度的区域。在这些区域中,声子像黑洞中的光一样被捕获,即使我们有离散的场论和非线性色散关系。我们研究了在这个装置中出现的霍金辐射,并提出了一个方案来检测它。

英文摘要:

In this article we propose to simulate acoustic black holes with ions in rings. If the ions are rotating with a stationary and inhomogeneous velocity profile, regions can appear where the ion velocity exceeds the group velocity of the phonons. In these regions phonons are trapped like light in black holes, even though we have a discrete field theory and a nonlinear dispersion relation. We study the appearance of Hawking radiation in this setup and propose a scheme to detect it.
