TQFT gravity dual to the orbifold groupoid of Narain code CFTs over
Rajae Sammani, Abdellah Sebbar
In a companion paper arXiv:2610.26610, we classified the Narain conformal field theories obtained by gluing copies of the root and weight lattices along their …
Optics and Thermodynamics of Charged BTZ Black Holes with Exotic Matter Sources
M. A. Rbah, S. Saoud, R. Sammani +2
We study a modified charged BTZ black hole in \((2+1)\)--dimensional anti-de Sitter spacetime, where the standard geometry is surrounded by quintessence-like anisotropic matter and…
Algebraic constructions of code lattices in Narain conformal field theories
E. H Saidi, R. Sammani
We give new results on the structure and representations of the three lattices relevant…
A Swampland-modified Hod bound for charged black holes with exotic matter
S. Saoud, M. A Rbah, R. Sammani +2
In this paper, we study the quasinormal modes (QNMs) of a charged black hole in the presence of both quintessence and a cloud of strings using the Pade-averaged higher-order WKB ap…
Multifield quintessential inflation and Swampland constraints in the IDM
S. Saoud, M. A. Rbah, R. Sammani +2
We investigate quintessential inflation in the Inert Doublet Model coupled to a light quintessence field through an exponential interaction. In the Einstein frame, the model forms…
Compactified 2HDM under the Non-SUSY AdS instability conjecture
M. A. Rbah, S. Saoud, R. Sammani +2
We investigate how extra-dimensional dynamics influence Higgs-sector phenomenology by compactifying a Two-Higgs-Doublet Model (2HDM) coupled to 4D gravity on a circle \(S^1\). The…
Minimal Weak Gravity Conjecture And Gauge Duality in M-theory on K3xT2
Mohammed Charkaoui, Rajae Sammani, El Hassan Saidi +1
The minimal Weak Gravity Conjecture (WGC) predicts the emergence of towers of superextremal states in both weak and strong coupling limits. In this work, we study M-theory compacti…
Landscape of Narain CFTs
R. Sammani, E. H Saidi, R. Ahl Laamara +1
In this work, we investigate the AdS gravitational bulk dual to an ensemble of Narain CFTs and their generalisations to establish bounds consistent with the Swampland program…
Code CFTs and Topological Matter
E. H Saidi, R. Sammani
In this paper, we propose a novel framework for modeling topological phases of matter using code-based Narain conformal field theories (NCFTs). We show that the algebraic structure…
Black hole solutions of three dimensional E-gravity
R. Sammani, E. H Saidi, R. Ahl Laamara
This paper aims to construct exceptional Banados-Teitelboim-Zanelli (BTZ) black holes carrying E charges as solutions to the 3D higher spin Anti-de Sitter (AdS) gravity with…
Fluctuating Ensemble Averages and the BTZ Threshold
R. Sammani, E. H Saidi, R. Ahl Laamara +1
Recent work shows fascinating links between ensemble averaging and the Swampland program. In order to break the emerging global symmetries of the ensemble averaging as dictated by…
Algebraic Realisation of the Zamolodchikov Metric in Narain Theories
El Hassan Saidi, Rajae Sammani
We revisit Narain conformal field theories from an algebraic perspective based on finite dimensional Lie algebras and representations , and s…
Topological 4D gravity and gravitational defects

Using the Chern-Simons formulation of AdS3 gravity as well as the Costello-Witten-Yamazaki (CWY) theory for quantum integrability, we construct a novel topological 4D gravity given…
Higher spin AdS gravity and Tits-Satake diagrams
Rajae Sammani, Youssra Boujakhrout, El Hassan Saidi +2
We investigate higher spin AdS gravity with real split forms of complex A B, C and D Lie algebras. This is done by linking spin multiplets w…

R. Sammani, E. H Saidi
In this paper, we show that a possible version of the swampland weak gravity conjecture for higher spin (HS) massive topological AdS gravity can be expressed in terms of mass…

R. Sammani, E. H Saidi
Using Chern-Simons formulation, we investigate higher spin (HS) black holes in AdS with soft Heisenberg hair and establish linkage with the real forms of the underlying compl…
Asymptotic Weak Gravity Conjecture in M-theory on K3 K3
M. Charkaoui, R. Sammani, E. H Saidi +1
The Asymptotic WGC has been proposed as a special case of the tower WGC that probes infinite distances in the moduli space corresponding to weakly coupled gauge regimes. The conjec…
