New Type IIB Poly-instanton Effects and Axion Quintessence
Luca Caraffi, Federico Carta, Michele Cicoli
Previous studies of poly-instantons in type IIB Calabi-Yau orientifolds found that these effects arise when Euclidean D3-branes wrap rigid cycles with a Wilson line. In this work,…
Fuzzy Axions and Associated Relics
Elijah Sheridan, Federico Carta, Naomi Gendler +6
We study fuzzy axion dark matter in type IIB string theory, for axions descending from the Ramond-Ramond four-form in compactifications on orientifolds of Calabi-Yau hypersurfaces.…
On brane systems with O planes -- 5d and 6d SCFTs
Mohammad Akhond, Guillermo Arias-Tamargo, Federico Carta +2
We study Higgs branches of field theories with 8 supercharges in 5 and 6 dimensions, focusing on theories realised on 5-brane webs in Type IIB with an O plane, or a D6-D8-NS5…
Comments on Non-invertible Symmetries in Argyres-Douglas Theories
Federico Carta, Simone Giacomelli, Noppadol Mekareeya +1
We demonstrate the presence of non-invertible symmetries in an infinite family of superconformal Argyres-Douglas theories. This class of theories arises from diagonal gauging of th…
A tale of 2-groups: D(USp(2N)) theories
Federico Carta, Simone Giacomelli, Noppadol Mekareeya +1
A 1-form symmetry and a 0-form symmetry may combine to form an extension known as the 2-group symmetry. We find the presence of the latter in a class of Argyres-Douglas theories, c…
Exploring the orthosymplectic zoo
Mohammad Akhond, Federico Carta, Siddharth Dwivedi +3
We study the Higgs branch of the SCFT limit of 5d SO(6) and SO(8) gauge theory with hypermultiplets in the spinor and vector representations. In the case of SO(6) gauge theories, w…
Dynamical consequences of 1-form symmetries and the exceptional Argyres-Douglas theories
Federico Carta, Simone Giacomelli, Noppadol Mekareeya +1
Higher-form symmetries have proved useful in constraining the dynamics of a number of quantum field theories. In the context of the Argyres-Douglas (AD) theories of the ty…
Systematics of perturbatively flat flux vacua for CICYs
Federico Carta, Alessandro Mininno, Pramod Shukla
In this paper, we extend the analysis of scanning the perturbatively flat flux vacua (PFFV) for the type IIB orientifold compactifications on the mirror of the projective complete…
Divisor topologies of CICY 3-folds and their applications to phenomenology
Federico Carta, Alessandro Mininno, Pramod Shukla
In this article, we present a classification for the divisor topologies of the projective complete intersection Calabi-Yau (pCICY) 3-folds realized as hypersurfaces in the product…
Systematics of perturbatively flat flux vacua
Federico Carta, Alessandro Mininno, Pramod Shukla
In this article, we present a systematic analysis of the so-called perturbatively flat flux vacua (PFFV) for the mirror Calabi-Yau (CY) -folds () with $h^{1,1}(\til…
Conformal Manifolds and 3d Mirrors of Theories
Federico Carta, Simone Giacomelli, Noppadol Mekareeya +1
The Argyres-Douglas (AD) theories of type , realized by type IIB geometrical engineering on a single hypersurface singularity, are studied. We analyze their conformal ma…
Thraxions: Towards Full String Models
Federico Carta, Alessandro Mininno, Nicole Righi +1
We elucidate various aspects of the physics of thraxions, ultra-light axions arising at Klebanov-Strassler multi-throats in the compactification space of IIB superstring theory. We…
Magnetic quivers from brane webs with O7-planes
Mohammad Akhond, Federico Carta
We consider the Higgs branch of 5d fixed points engineered using brane webs with an O7-plane. We use the brane construction to propose a set of rules to extract the correspondi…
Conformal Manifolds and 3d Mirrors of Argyres-Douglas theories
Federico Carta, Simone Giacomelli, Noppadol Mekareeya +1
Argyres-Douglas theories constitute an important class of superconformal field theories in d. The main focus of this paper is on two infinite families of such theories, known as…
Factorised 3d orthosymplectic quivers
Mohammad Akhond, Federico Carta, Siddharth Dwivedi +3
We study the moduli space of 3d quiver gauge theories with unitary, orthogonal and symplectic gauge nodes, that fall into exceptional sequences. We find that both t…
Gopakumar-Vafa Hierarchies in Winding Inflation and Uplifts
Federico Carta, Alessandro Mininno, Nicole Righi +1
We propose a combined mechanism to realize both winding inflation and de Sitter uplifts. We realize the necessary structure of competing terms in the scalar potential not via tunin…
Resolving spacetime singularities in flux compactifications & KKLT
Federico Carta, Jakob Moritz
In flux compactifications of type IIB string theory with D3 and seven-branes, the negative induced D3 charge localized on seven-branes leads to an apparently pathological profile o…
Five-brane webs, Higgs branches and unitary/orthosymplectic magnetic quivers
Mohammad Akhond, Federico Carta, Siddharth Dwivedi +3
We study the Higgs branch of 5d superconformal theories engineered from brane webs with orientifold five-planes. We propose a generalization of the rules to derive magnetic quivers…
Harmonic Hybrid Inflation
Federico Carta, Nicole Righi, Yvette Welling +1
We present a mechanism for realizing hybrid inflation using two axion fields with a purely non-perturbatively generated scalar potential. The structure of scalar potential is highl…
A landscape of orientifold vacua
Federico Carta, Jakob Moritz, Alexander Westphal
We present a vast landscape of O3/O7 orientifolds that descends from the famous set of complete intersection Calabi-Yau threefolds (CICY). We give distributions of topological data…
No go for a flow
Federico Carta, Alessandro Mininno
We prove that a very large class of general Argyres-Douglas theories cannot admit a UV lagrangian which flows to them via the Maruyoshi-Song supersymmetry enhancement mecha…
The Geometry of SUSY Enhancement
Federico Carta, Simone Giacomelli, Hirotaka Hayashi +1
We provide a precise geometric picture that demystifies the phenomenon of supersymmetry enhancement along certain RG flows of four-dimensional field theories, recently discovered b…
Gaugino condensation and small uplifts in KKLT
Federico Carta, Jakob Moritz, Alexander Westphal
In the first part of this note we argue that ten dimensional consistency requirements in the form of a certain tadpole cancellation condition can be satisfied by KKLT type vacua of…
