喉咙的温度

Temperature in the Throat

Dariush Kaviani, Amir Esmaeil Mosaffa

摘要:

我们研究了弦论中扩展物体的温度。旋转的探测D膜承认了翁鲁效应的视界和温度。我们发现,即使在体卡-丘系统中没有黑洞,包含弯曲卡-丘喉道的全息弦解中,慢旋转探测D1-膜上的诱导度规也具有明显的热视界和特征霍金温度.以紫外/红外极限的解决方案,我们表明,世界体积的黑洞成核依赖于变形和翘曲的喉咙。我们发现,世界体积的地平线和预期功能的温度形式不是在经常限制红外区域,但在奇异的非限制紫外线的解决方案。在共形限制的紫外线,我们发现地平线和温度类似的旋转探头在AdS喉在文献中发现。在这种情况下,我们还发现,从U(1)R对称性激活一个背景规范场改变了诱导度规,其温度描述了两类不同的黑洞解。

英文摘要:

We study the temperature of extended objects in string theory. Rotating probe D-branes admit horizons and temperatures a la Unruh effect. We find that the induced metrics on slow rotating probe D1-branes in holographic string solutions including warped Calabi-Yau throats have distinct thermal horizons with characteristic Hawking temperatures even if there is no black hole in the bulk Calabi-Yau. Taking the UV/IR limits of the solution, we show that the world volume black hole nucleation depends on the deformation and the warping of the throat. We find that world volume horizons and temperatures of expected features form not in the regular confining IR region but in the singular nonconfining UV solution. In the conformal limit of the UV, we find horizons and temperatures similar to those on rotating probes in the AdS throat found in the literature. In this case, we also find that activating a background gauge field form the U(1) R--symmetry modifies the induced metric with its temperature describing two different classes of black hole solutions.
