AI 中文摘要
将卡拉比-丘（Calabi-Yau）几何映射到早期宇宙宇宙学仍是弦现象学的主要目标。本文提出一种暴胀机制，其中通量稳态改变场动力学，在霍奇边界附近沿控制体积的轴子类标量场（saxion）方向驱动暴胀。该区域的内禀几何严格决定标量势，此设置可使场免受重模修正影响，且无需消耗额外的通量 tadpoles（通量反常项）。结果，几何边界的特性直接转化为原初张量扰动，建立起弦紧化到可测量数据的清晰物理联系。所得几何预测符合当前宇宙微波背景（CMB）限制，并为即将开展的 LiteBIRD 和 CMB-S4 观测提供具体可检验的目标。
英文摘要
Mapping Calabi-Yau geometry to early Universe cosmology remains a primary goal in string phenomenology. We present an inflationary mechanism where flux stationarity shifts the field dynamics, driving inflation along the volume-controlling saxion direction near a Hodge boundary. In this region, the internal geometry strictly dictates the scalar potential. This setup stabilizes the field against heavy moduli corrections without consuming extra flux tadpoles. As a result, the properties of the geometric boundary translate directly into primordial tensor perturbations, creating a clear physical link from string compactifications to measurable data. The resulting geometric predictions match current cosmic microwave background limits and provide specific, testable targets for upcoming LiteBIRD and CMB-S4 observations.
