用高维黑洞类似物探测额外维度?
Probing extra dimensions with higher dimensional black hole analogues?
摘要:
我们提出,额外的维度可能会检测到更高维的类似黑洞。将通常的四维声(音)黑洞度规推广到任意维。在半经典近似下计算了霍金辐射在膜上和体中的吸收截面。
英文摘要:
We propose that extra dimensions might be detected with higher dimensional analogues of black holes. The usual 4-dimensional acoustic(sonic)black hole metric is extended to arbitrary dimensions. The absorption cross-section of Hawking radiation on the brane and in the bulk are calculated in the semiclassical approximation.
