Axion-Scalar Systems and Dynamical Distances
Thomas W. Grimm, Damian van de Heisteeg, Filippo Revello
We study the cosmology of axion-scalar pairs, coupled by a hyperbolic field-space metric and with a string-motivated rational scalar potential. Borrowing tools from the theory of d…
Symmetries and M-theory-like Vacua in Four Dimensions
Shi Chen, Damian van de Heisteeg, Cumrun Vafa
Non-geometric flux vacua have recently been revisited, leading to the remarkable discovery of isolated 4D supersymmetric Minkowski vacua. These constructions rely…
Finiteness and the Emergence of Dualities
Matilda Delgado, Damian van de Heisteeg, Sanjay Raman +3
We argue that the finiteness of quantum gravity amplitudes in fully compactified theories (at least in supersymmetric cases) leads to a bottom-up prediction for the existence of no…
Charting the Complex Structure Landscape of F-theory
Damian van de Heisteeg
We explore the landscape of F-theory compactifications on Calabi--Yau fourfolds whose complex structure moduli space is the thrice-punctured sphere. As a first part, we enumerate a…
Species Scale in Diverse Dimensions
Damian van de Heisteeg, Cumrun Vafa, Max Wiesner +1
In a quantum theory of gravity, the species scale can be defined as the scale at which corrections to the Einstein action become important or alternatively as codifying the…
Exact Flux Vacua, Symmetries, and the Structure of the Landscape
Thomas W. Grimm, Damian van de Heisteeg
Identifying flux vacua in string theory with stabilized complex structure moduli presents a significant challenge, necessitating the minimization of a scalar potential complicated…
