Mass Hierarchies and Dynamical Field Range
Aitor Landete, Gary Shiu
Several swampland conjectures suggest that there is a critical field range beyond which the effective field theory (EFT) description breaks down in quantum gravity. In applications…
Flux Flattening in Axion Monodromy Inflation
Aitor Landete, Fernando Marchesano, Gary Shiu +1
String theory models of axion monodromy inflation exhibit scalar potentials which are quadratic for small values of the inflaton field and evolve to a more complicated function for…
Challenges for D-brane large-field inflation with stabilizer fields
Aitor Landete, Fernando Marchesano, Clemens Wieck
We study possible string theory compactifications which, in the low-energy limit, describe chaotic inflation with a stabilizer field. We first analyze type IIA setups where the inf…
D6-branes and axion monodromy inflation
Dagoberto Escobar, Aitor Landete, Fernando Marchesano +1
We develop new scenarios of large field inflation in type IIA string compactifications in which the key ingredient is a D6-brane that creates a potential for a B-field axion. The p…
Large field inflation from D-branes
Dagoberto Escobar, Aitor Landete, Fernando Marchesano +1
We propose new large field inflation scenarios built on the framework of F-term axion monodromy. Our setup is based on string compactifications where D-branes create potentials for…
