Phenomenologically, rapid-turn inflation models have been shown to be attractor solutions with at least linear stability of the perturbations by Bjorkmo (2019). In addition, srrt inflation has successfully been embedded in supergravity (Aragam et al., 2022) and simple string theory (Chakraborty et al., 2020) models. Thus, it is becoming increasingly valuable for theorists to test if their models are suitable for srrt inflation. Anguelova and Lazaroiu (2023) have derived a consistency condition purely in terms of the potential and metric of the scalar manifold for two-field inflation models. In this thesis, their consistency condition will be re-derived. In addition, we will present the inflatox python package with a numerical implementation of the consistency condition. We used inflatox to analyze four different two-field inflation models: Orbital inflation (Achúcarro et al., 2020), angular inflation (Christodoulidis et al., 2019), the egno supergravity model (Ellis et al., 2014) and a D5-brane fat inflation model from string theory (Chakraborty et al., 2020). For two of these models, we were able to numerically obtain srrt trajectories using PyTransport (Dias et al., 2016) and confirm that these trajectories overlap with the region in field space where the consistency condition holds.Show less
