向非对易膜暴胀又迈进了一步

One more step toward the noncommutative brane inflation

Kourosh Nozari, Siamak Akhshabi

摘要:

最近,利用时空非对易性的模糊相干态图像,构造了一种新的暴胀方案。在这里,我们将这一观点推广到兰德尔-桑德拉姆II膜世界场景。这个模型实现了一个暴胀,反弹的解决方案,而不求助于任何腋标量或矢量场。该模型不存在初始奇异性,具有产生标量扰动的尺度不变谱的潜力。

英文摘要:

Recently a new approach to inflation proposal has been constructed via the smeared coherent state picture of spacetime noncommutativity. Here we generalize this viewpoint to a Randall-Sundrum II braneworld scenario. This model realizes an inflationary, bouncing solution without recourse to any axillary scalar or vector fields. There is no initial singularity and the model has the potential to produce scale invariant spectrum of scalar perturbations.
