本文在大Hubble尺度和有利的张量标量比r ≥ 0.05的条件下,研究了杂化轨道紧致化中的模稳定化和暴胀化。为了解释跨普朗克场范围,我们实现了对齐的自然暴胀。虽然在杂合结构中只有一个普适轴子,但是来自几何模的更多轴子可以用于对齐和膨胀。我们认为,这样的排列是相当普遍的orbifolds,因为所有的非微扰项所涉及的领域和Dedekind η函数的模权确定。我们提出了两个设置的灵感来自迷你景观模型的106 − II orbifold,实现对齐的通货膨胀和稳定的相关模量。一个在暴胀后有一个超对称真空,而另一个则包含一个在高尺度下打破超对称的高根诺凝聚。
A bstractWe study moduli stabilization in combination with inflation in heterotic orbifold compactifications in the light of a large Hubble scale and the favored tensor-to-scalar ratio r ≈ 0.05. To account for a trans-Planckian field range we implement aligned natural inflation. Although there is only one universal axion in heterotic constructions, further axions from the geometric moduli can be used for alignment and inflation. We argue that such an alignment is rather generic on orbifolds, since all non-perturbative terms are determined by modular weights of the involved fields and the Dedekind η function. We present two setups inspired by the mini-landscape models of the ℤ6 − II orbifold which realize aligned inflation and stabilization of the relevant moduli. One has a supersymmetric vacuum after inflation, while the other includes a gaugino condensate which breaks supersymmetry at a high scale.
