声黑洞霍金辐射的Anomaly分析

Anomaly Analysis of Hawking Radiation from Acoustic Black Hole

Wontae Kim, Hyeonjoon Shin

摘要:

从Robinson和Wilczek提出的反常抵消方法出发,研究了三维旋转声黑洞的霍金辐射.视界附近的量子场可用二维带电场来描述,带电量记为角动量m。由反常抵消条件和视界处的正则性得到了电荷和能量的通量,并与Hawking温度下的二维黑体辐射的通量相匹配.

英文摘要:

The Hawking radiation from the three dimensional rotating acoustic black hole is considered from the viewpoint of anomaly cancellation method initiated by Robinson and Wilczek. Quantum field near the horizon is effectively described by two dimensional charged field with a charge identified as the angular momentum m. The fluxes of charge and energy are obtained from the anomaly cancellation condition and regularity at the horizon, and are shown to match with those of the two dimensional black body radiation at the Hawking temperature.
