ACT Implications for Hilltop Inflation
Monika Lynker, Rolf Schimmrigk
We analyze in a systematic way the implications for the classes of hilltop and hilltop-squared inflation of the recent DR6 observations by the Atacama Cosmology Telescope collabora…
Special Fano geometry from Feynman integrals
Rolf Schimmrigk
One of the fundamental open questions in QFT is what kind of functions appear as Feynman integrals. In recent years this question has often been considered in a geometric context b…
Scaling Characteristics of Hilltop and Hilltop-Squared Inflation
Monika Lynker, Rolf Schimmrigk
One of the longstanding goals in the framework of inflation is the construction of tools that can be used to classify models in theory space. An idea that has been put forward in t…
Scaling behavior of observables as a model characteristic in multifield inflation
Monika Lynker, Rolf Schimmrigk
One of the fundamental questions in inflation is how to characterize the structure of different types of models in the field theoretic landscape. Proposals in this direction includ…
Large and small field inflation from hyperbolic sigma models
Rolf Schimmrigk
Long standing themes in inflation include the issue of large field vs. small field inflation as well as the question what fraction of phase space leads to sufficient inflation, and…
Flux vacua and modularity
Rolf Schimmrigk
Geometric modularity has recently been conjectured to be a characteristic feature for flux vacua with . This paper provides support for the conjecture by computing motivic mod…
