基本质粒弦和黑环

Fundamental Plasmid Strings and Black Rings

Jose J. Blanco-Pillado, Roberto Emparan, Alberto Iglesias

摘要:

我们构造了基本弦的激发态,它可以用弦的旋转圆环作半经典描述。我们将它们与旋转偶极环的超引力解相一致。识别涉及两个系统的质量、半径和角动量的精确匹配。此外,弦态的简并性再现了超引力描述中熵的参数依赖性。当解具有两个宏观角动量时,它们更好地描述为环形配置(管状环)而不是弦环。我们认为,弦态的衰变可以解释为超辐射发射的量子从各能区的旋转环。

英文摘要:

We construct excited states of fundamental strings that admit a semiclassical description as rotating circular loops of string. We identify them with the supergravity solutions for rotating dipole rings. The identification involves a precise match of the mass, radius and angular momentum of the two systems. Moreover, the degeneracy of the string state reproduces the parametric dependence of the entropy in the supergravity description. When the solutions possess two macroscopic angular momenta, they are better described as toroidal configurations (tubular loops) instead of loops of string. We argue that the decay of the string state can be interpreted as superradiant emission of quanta from the ergoregion of the rotating ring.
