M-theory boundaries beyond supersymmetry
Miguel Montero, Luis Zapata
The chiral worldvolume theory of an M-theory boundary (the so-called M9 brane) is uniquely determined by supersymmetry and anomaly inflow. In this brief note we investigate whether…

To curve, or not to curve: Is curvature-assisted quintessence observationally viable?
George Alestas, Matilda Delgado, Ignacio Ruiz +3
Single-field models of accelerated expansion with nearly flat potentials, despite being able to provide observationally viable explanations for the early-time cosmic inflation and…

Global anomalies & bordism of non-supersymmetric strings
Ivano Basile, Arun Debray, Matilda Delgado +1
The three tachyon-free non-supersymmetric string theories in ten dimensions provide a handle on quantum gravity away from the supersymmetric lamppost. However, they have not been s…
