论文摘要
我们将经典的双复制程序应用于一类常规的非明量黑洞解决方案。我们给出了几个例子，特别关注了T-Duality从T-偶然出现的弦理论校正的黑洞解决方案。非扰动的弦乐校正引入了紫外线（UV）零点长度截止，从而导致了非单明的黑洞空位。除了紫外线调节器外，该解决方案还等同于Bardeen Black Hole时空。我们扩展了该解决方案，以包括渐近DE Sitter背景。所有与双拷贝相关的Yang-Mills字段理论数量均为所有参数值均具有良好的行为且有限。我们对黑洞地平线结构进行了彻底的分析，此外，还发现了重力侧的地平线与双拷贝仪表侧的电场之间的简单新连接。
We apply the classical double copy procedure to a class of regular, non-singular black hole solutions. We give several examples, paying particular attention to a string-theory-corrected black hole solution emerging from T-duality. Non-perturbative stringy corrections introduce an ultraviolet (UV) zero-point length cutoff which results in non-singular black hole spacetimes. Apart from the UV regulator, the solution is equivalent to the Bardeen black hole spacetime. We extend this solution to include an asymptotic de Sitter background. All Yang-Mills field theory quantities associated with the double copy are well-behaved and finite for all values of parameters. We present a thorough analysis of the black hole horizon structure, additionally uncovering a simple yet new connection between horizons on the gravity side and electric fields on the gauge theory side of the double copy.
