穿透流体力学白洞的视界
Penetrating the horizon of a hydrodynamic white hole
AI总结：
本研究针对浅水流径向出流中的流体力学白洞视界，揭示了黏性引发的圆形水跃构成视界屏障，表面张力既导致波在视界堆积又使波能以衰减振幅隧穿，且视界可能存在大振幅不稳定性。
摘要：
在浅水流径向出流中，流体力学白洞的视界与驻立的圆形水跃重合。该水跃由黏性引发，使视界以圆形波前的形式显现，作为阻挡波进入其圆周内部的屏障。波的受阻会导致白洞视界处出现波的堆积，这一现象主要由表面张力导致。反过来，也正是因为表面张力，波能够穿透这道屏障。穿透的波（类比霍金量子）以振幅衰减的方式隧穿屏障，但视界周围可能出现大振幅的不稳定性。
英文摘要：
In a shallow-water radial outflow the horizon of a hydrodynamic white hole coincides with a standing circular hydraulic jump. The jump, caused by viscosity, makes the horizon visible as a circular front, standing as a barrier against the entry of waves within its circumference. The blocking of waves causes a pile-up at the horizon of the white hole, for which surface tension is mainly responsible. Conversely, it is also because of surface tension that the waves can penetrate the barrier. The penetrating waves (analogue Hawking quanta) tunnel through the barrier with a decaying amplitude, but a large-amplitude instability about the horizon is possible.
