标题： Spinflation and cycling branes in warped throats

摘要： 在Calabi-Yau通量紧致化中，膜在角方向上的运动的含义从生活在膜世界体积上的观察者的观点和从生活在三个非紧致维中的其他观察者的观点进行了讨论。 膜观察者可以体验到由离心角动量屏障引起的尺度因子的宇宙反弹和循环行为。 在紧致化中其他地方生活的观察者由于大的角动量（自旋膨胀）而经历略微延长的暴胀时期。 在暴胀期间存在自旋膨胀场（或其他具有非标准动能项的场）可能会导致宇宙微波背景辐射中的有趣观测特征。 显示英文摘要

摘要： The implications of brane motion in angular directions of Calabi-Yau flux compactifications are discussed from the point of view of an observer living on the worldvolume of the brane and from the point of view of an observer living elsewhere in the three non-compact dimensions. The brane observer can experience cosmological bounces and cyclic behavior of the scale factor induced by centrifugal angular momentum barriers. Observers living elsewhere in the compactification experience marginally prolonged periods of inflation due to large angular momentum (spinflation). The presence of spinflaton fields (or other fields with non-standard kinetic terms) during inflation may lead to interesting observational signatures in the cosmic microwave background radiation.
