Search for Inflationary Attractors

Bachelor thesis | Natuurkunde (BSc)

In 2018, Achúcarro et al. presented a class of two-field inflationary models known as ’shift-symmetric orbital inflation’. These models have multi-field behaviour but their predictions remain very close to those of single-field inflation. This thesis will first introduce the topic of inflation, provide background to the field and build the necessary equations and concepts starting at the foundations of cosmology. Then it shall further examine these models and their solutions. Stability will be proven for a small subset of the class. Furthermore, a few sufficient sets of requirements for stability will be presented. It will be argued, but not proven, that stability holds in general.
