用新的动量载流子解析黑洞微结构
Resolving Black-Hole Microstructure with New Momentum Carriers
摘要：
所有已知的无视界黑洞微观态几何都对应于获得有限尺寸的膜源，因此破坏了黑洞的球对称性。我们构造，为第一次，零视界面积的解决方案，具有相同的电荷作为一个三电荷F1-NS 5-P型IIA黑洞和保持这种球对称性。这些解的动量由NS 5-膜内部的纵向D 0-D4密度涨落携带。我们认为，这些解决方案应被解释为一个家庭的光滑，horizonless微观几何形状，称为superstrata，在这种几何退化的长喉极限。这些几何的存在表明，即使在三电荷微态几何的模空间的奇异角上也不会出现有限尺寸的视界。
英文摘要：
All known horizonless black-hole microstate geometries correspond to brane sources that acquire a finite size, and hence break the spherical symmetry of the black hole. We construct, for the first time, solutions with zero horizon area that have the same charges as a three-charge F1-NS5-P Type-IIA black hole and preserve this spherical symmetry. The momentum of these solutions is carried by longitudinal D0-D4 density fluctuations inside the NS5-branes. We argue that these solutions should be interpreted as the long-throat limit of a family of smooth, horizonless microstate geometries, called superstrata, where such geometries degenerate. The existence of these geometries indicates that a finite-size horizon does not appear even in the singular corners of the moduli space of three-charge microstate geometries.
