The backreaction equations for the linearized quantum fluctuations in an acoustic black hole are given. The solution near the horizon, obtained within a dimensional reduction, indicates that acoustic black holes, unlike Schwarzschild ones, get cooler as they radiate phonons. They show remarkable analogies with near-extremal Reissner-Nordström black holes.
给出了声学黑洞中线性化量子涨落的反作用方程。在维数约化中得到的视界附近的解表明,与史瓦西黑洞不同,声学黑洞在辐射声子时会变冷。它们与近极端雷斯纳 - 诺德斯特龙黑洞有显著的相似之处。
