论文摘要
我们构建O（16）XO（16）杂种弦的非超对称ADS3溶液。大多数背景具有经典的世界表格定义，但在字符串环更正会改变时空的曲率的意义上是量子字符串真空。在一环上，宇宙常数的变化是积极的，但永远不足以提升到保姆空间。通过计算时空标量的频谱，我们表明在BF结合下没有Tachyons。我们还表明，有一个没有时空NS-NS通量的解决方案。该背景没有经典的字符串限制。令人惊讶的是，似乎对这些构造有参数控制，这为探索量子重力和全息图提供了一个框架，而无需超对称性。
We construct non-supersymmetric AdS3 solutions of the O(16)xO(16) heterotic string. Most of the backgrounds have a classical worldsheet definition but are quantum string vacua in the sense that string loop corrections change the curvature of spacetime. At one-loop, the change in the cosmological constant is positive but never sufficient to uplift to de Sitter space. By computing the spectrum of spacetime scalars, we show that there are no tachyons below the BF bound. We also show that there is a solution with no spacetime NS-NS flux. This background has no classical string limit. Surprisingly, there appears to be parametric control over these constructions, which provide a framework for exploring quantum gravity and holography without supersymmetry.
