Large Field Inflation from Axion Mixing
Gary Shiu, Wieland Staessens, Fang Ye
We study the general multi-axion systems, focusing on the possibility of large field inflation driven by axions. We find that through axion mixing from a non-diagonal metric on the…
Widening the Axion Window via Kinetic and Stückelberg Mixings
Gary Shiu, Wieland Staessens, Fang Ye
We point out that kinetic and Stückelberg mixings that are generically present in the low energy effective action of axions can significantly widen the window of axion decay consta…
Milli-Charged Dark Matter in Quantum Gravity and String Theory
Gary Shiu, Pablo Soler, Fang Ye
We examine the milli-charged dark matter scenario from a string theory perspective. In this scenario, kinetic and mass mixings of the photon with extra U(1) bosons are claimed to g…
Soft branes in supersymmetry-breaking backgrounds
Paul McGuirk, Gary Shiu, Fang Ye
We revisit the analysis of effective field theories resulting from non-supersymmetric perturbations to supersymmetric flux compactifications of the type-IIB superstring with an eye…
