A note on the holographic consistency of DGKT-type vacua with
Filippo Revello, Farah Verbeure
Recent works have pointed out the existence of a holographic constraint on (extremal) three-point functions of scalar moduli in scale-separated AdS vacua. Moreover, it has been sho…
A Holographic Constraint on Scale Separation
Nikolay Bobev, Hynek Paul, Filippo Revello
We propose a new consistency condition for the compatibility of a gravitational effective field theory in AdS with a dual holographic description in terms of a family of large-…
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…
String Theory and the First Half of the Universe
Fien Apers, Joseph P. Conlon, Edmund J. Copeland +2
We perform a detailed study of stringy moduli-driven cosmologies between the end of inflation and the commencement of the Hot Big Bang, including both the background and cosmologic…
Attractive (s)axions: cosmological trackers at the boundary of moduli space
Filippo Revello
We study the cosmological evolution of a FLRW universe dominated by the energy density of moduli close to asymptotic regions of moduli space. Due to the structure of the $\mathcal{…
Kination, Meet Kasner: On The Asymptotic Cosmology of String Compactifications
Fien Apers, Joseph P. Conlon, Martin Mosny +1
We study runaway, kination-dominated epochs in string cosmology. We show how the apparent classical decompactification runaway of the volume modulus, described by a kination epoch…
