摘要:

本文研究了声学黑洞时空背景下的大质量旋量场的动力学。虽然这个有效的度量是声学的,描述了声波的传播,但它可以被认为是引力黑洞的玩具模型。在这种方式下,我们研究的费米子场的动力学性质,在这个“引力”旋转黑洞以及旋涡背景。我们计算的微分截面,通过使用分波的方法,并表明类似的引力Aharonov-Bohm效应发生的大质量费米子场移动在这个有效的度规。我们讨论了极限情形,并将结果与无质量标量场情形进行了比较。

英文摘要:

In this paper we consider the dynamics of a massive spinor field in the background of the acoustic black hole spacetime. Although this effective metric is acoustic and describes the propagation of sound waves, it can be considered as a toy model for the gravitational black hole. In this manner, we study the properties of the dynamics of the fermion field in this "gravitational" rotating black hole as well as the vortex background. We compute the differential cross section through the use of the partial wave approach and show that an effect similar to the gravitational Aharonov-Bohm effect occurs for the massive fermion field moving in this effective metric. We discuss the limiting cases and compare the results with the massless scalar field case.
