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…
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…
Optically Controlled Topological Phases in the Deformed Lattice
Othmane Benhaida, El Hassan Saidi, L. B. Drissi
Haldane's tight-binding model, which describes a Chern insulator in a two-dimensional hexagonal lattice, exhibits quantum Hall conductivity without an external magnetic field. Here…
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…
Topological Properties of Bilayer Lattice Induced by Polarized Light
O. Benhaida, E. H. Saidi, L. B. Drissi +1
We investigate the topological properties of photon-dressed energy bands in bilayer lattices under off-resonant circularly polarized light, focusing on aligned and cyclic…
A signature index for third order topological insulators
L. B Drissi, E. H Saidi
In this work, we develop an index signature characterising the third order topological phases in 3D systems. This index is an alternating sum of monomial signatures of Higgs triple…
