模与多场暴胀

Moduli and multi-field inflation

Zygmunt Lalak

摘要:

具有平坦或失控经典势的模在基于超对称性和额外维度的理论中是通用的。它们在动力学项和非微扰超势中相互混合,并与物质场混合。结果,标量势中出现了有趣的结构,这有助于稳定和捕获模,并导致多场暴胀。多重暴胀系统的新的和有吸引力的特征是等曲率扰动,它可以以一种有趣的方式修改暴胀导致的原始波动的最终谱。

英文摘要:

Moduli with flat or run-away classical potentials are generic in theories based on supersymmetry and extra dimensions. They mix between themselves and with matter fields in kinetic terms and in the nonperturbative superpotentials. As the result, interesting structure appears in the scalar potential which helps to stabilise and trap moduli and leads to multi-field inflation. The new and attractive feature of multi-inflationary setup are isocurvature perturbations which can modify in an interesting way the final spectrum of primordial fluctuations resulting from inflation.
