Valley- and Orbital-Controlled 2D Chern Insulators Without Spin-orbit Interaction

J. Benkaida, O. Benhaida, L. B. Drissi +1

We present a theoretical study of orbital-induced topological phase transitions in a two-dimensional lattice model with staggered potential and orbital coupling competi…

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…

Extended Haldane Model in The Dice Lattice: Multiple Flat-Band-Induced topological Transitions Revealed

Othmane Benhaida, Lalla Btissam Drissi, El Hassan Saidi

In this study, we examine the introduction of the Haldane model into the dice lattice by altering the flow between the next-nearest-neighbour sites. This breaks the lattice's inver…

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…

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…
