克尔-费米海

The Kerr-Fermi Sea

Thomas Hartman, Wei Song, Andrew Strominger

摘要:

在克尔黑洞附近存在一个大质量的标量场,它会产生与束缚超辐射模有关的不稳定性。在本文中,我们表明,大规模的费米子,而不是诱导的不稳定性,约束超辐射模式凝聚,形成一个费米海,以及以外的能层延伸。在半经典WKB近似下,解析计算了费米海在相空间中的形状和其他各种性质。黑洞附近的低能有效理论用费米面的波纹来描述。导出了它们的色散关系和对进入海中的粒子的有效力的表达式。

英文摘要:

The presence of a massive scalar field near a Kerr black hole is known to produce instabilities associated with bound superradiant modes. In this paper we show that for massive fermions, rather than inducing an instability, the bound superradiant modes condense and form a Fermi sea which extends well outside the ergosphere. The shape of this Fermi sea in phase space and various other properties are analytically computed in the semiclassical WKB approximation. The low energy effective theory near the black hole is described by ripples in the Fermi surface. Expressions are derived for their dispersion relation and the effective force on particles which venture into the sea.
