In this paper we consider the acoustic metric obtained from an Abelian Higgs model extended with higher derivative terms in the bosonic sector which describes an acoustic rotating black hole and analyze the phenomena of superresonance, analogue Aharonov–Bohm effect and absorption. We investigate these effects by computing the scalar wave scattering by a draining bathtub vortex and discuss the physical interpretation of higher derivative terms. Furthermore, we show that the absorption does not vanish as the draining parameter tends to zero.

高导模拟 Aharonov-Bohm 效应、吸收和超共振

在本文中，我们考虑从 Abelian Higgs 模型获得的声学度量，该模型在玻色子扇区中扩展了更高的导数项，该模型描述了声学旋转黑洞，并分析了超共振、模拟 Aharonov-Bohm 效应和吸收现象。我们通过计算排水浴缸涡流的标量波散射来研究这些影响，并讨论更高导数项的物理解释。此外，我们表明，当排水参数趋于零时，吸收不会消失。
