场论中某些快子效应的模拟流体模型

An analog fluid model for some tachyonic effects in field theory

E. Arias, C. H. G. Bessa, N. F. Svaiter

摘要:

我们考虑了在静止流体中沿超声(类空间)轨迹运动的点状声源的声辐射。我们称之为超声波源。我们描述了这种超声源发出的辐射。在对声扰动进行量子化之后,我们给出了由这种经典的快子源产生的声子的分布和经典的波干涉图样。

英文摘要:

We consider the sound radiation from an acoustic point-like source moving along a supersonic ("space-like") trajectory in a fluid at rest. We call it an acoustic "tachyonic" source. We describe the radiation emitted by this supersonic source. After quantizing the acoustic perturbations, we present the distribution of phonons generated by this classical tachyonic source and the classical wave interference pattern.
