论文摘要
我们使用纵向T-偶（作为一种溶液生成技术，构建了非相关字符串理论的基本Neveu-Schwarz（NS）Brane解决方案。将NS背景字段扩展到超级多重多集，我们验证我们发现的所有解决方案是否为半超对称性。我们发现两种扰动解决方案都将其解释为类似弦的对象外的背景几何形状。相应地，我们将这些非Lorentzian背景称为绕组字符串和Unwound String解决方案。尽管绕组弦是非相关字符串理论的壳频谱的一部分，但解体弦仅在介导瞬时引力力的地方才有意义。从九维的角度来看，我们发现绕组串解决方案是由非相关的巨大粒子来源的，并且Unwound弦溶液由零颜色和旋转的无质量的galilean粒子来源。我们解释了这两个字符串解决方案如何符合字符串理论的离散的轻酮量化。我们很快就会讨论基本的NS五元和kaluza-klein单极溶液，并表明它们都是半up的。
We construct the basic Neveu-Schwarz (NS) brane solutions of non-relativistic string theory using longitudinal T-duality as a solution generating technique. Extending the NS background fields to a supergravity multiplet, we verify that all solutions we find are half-supersymmetric. The two perturbative solutions we find both have an interpretation as the background geometry outside a string-like object. Correspondingly, we refer to these non-Lorentzian backgrounds as winding string and unwound string solution. Whereas the winding string is part of the on-shell spectrum of non-relativistic string theory, the unwound string only makes sense off-shell where it mediates the instantaneous gravitational force. Seen from the nine-dimensional point of view, we find that the winding string solution is sourced by a non-relativistic massive particle and that the unwound string solution is sourced by a massless Galilean particle of zero colour and spin. We explain how these two string solutions fit into a discrete lightcone quantization of string theory. We shortly discuss the basic NS five-brane and Kaluza-Klein monopole solutions and show that they are both half-supersymmetric.
