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…
Catch-Me-If-You-Can: The Overshoot Problem and the Weak/Inflation Hierarchy
Joseph P. Conlon, Filippo Revello
We study the overshoot problem in the context of post-inflationary string cosmology (in particular LVS). LVS cosmology features a long kination epoch as the volume modulus rolls do…
Integer solutions to the anomaly equations for a class of chiral gauge theories
Alessandro Podo, Filippo Revello
We find all the integer charge solutions to the equations for the cancellation of local gauge anomalies in a class of gauge theories which extend the Standard Model (SM) by a gauge…
Integer Conformal Dimensions for Type IIA Flux Vacua
Fien Apers, Joseph P. Conlon, Sirui Ning +1
We give a concise argument that supersymmetric AdS type IIA DGKT flux vacua on general Calabi-Yaus have, interpreted holographically, integer conformal dimensions for low-lying sca…
Chiral models of composite axions and accidental Peccei-Quinn symmetry
Roberto Contino, Alessandro Podo, Filippo Revello
We introduce a class of composite axion models that provide a natural solution to the strong CP problem, and possibly account for the observed dark matter abundance. The QCD axion…
Exploring The Holographic Swampland
Joseph P. Conlon, Sirui Ning, Filippo Revello
We extend studies of holographic aspects of moduli stabilisation scenarios to both fibred versions of LVS and the type IIA DGKT flux vacua. We study the holographic properties of t…
Composite Dark Matter from Strongly-Interacting Chiral Dynamics
Roberto Contino, Alessandro Podo, Filippo Revello
A class of chiral gauge theories is studied with accidentally-stable pseudo Nambu-Goldstone bosons playing the role of dark matter (DM). The gauge group contains a vector-like dark…
Moduli Stabilisation and the Holographic Swampland
Joseph P. Conlon, Filippo Revello
We investigate whether Swampland constraints on the low-energy dynamics of weakly coupled, moduli-stabilised string vacua in AdS can be related to inconsistencies of their putative…
