Structural, electronic and topological properties of 3D TmBi compound
M. Ragragui, L. B. Drissi, S. Lounis +1
Using density functional theory based methods we report the structural, electronic and topological properties of the FCC crystal compound TmBi. This material is found to be dynamic…
Higher order topological matter and fractional chiral states
L. B. Drissi, S. Lounis, E. H. Saidi
We develop a chiral anomalous fermion hamiltonian proposal to study the higher order topological (HOT) phase with chiral symmetry fractionalized like $\mathcal{C}_{x}…
Minuscule ABCDE Lax Operators from 4D Chern-Simons Theory
Youssra Boujakhrout, El Hassan Saidi
Using 4D Chern-Simons (CS) theory with gauge symmetry having minuscule coweights, we develop a suitable operator basis to deal with the explicit calculation of the Lax operator…
Magnetic Skyrmions: Theory and Applications
Lalla Btissam Drissi, El Hassan Saidi, Mosto Bousmina +1
Using the field theory method and coherent spin state approach, we investigate properties of magnetic solitons in spacetime while focussing on 1D kinks, 2D and 3D skyrmions. We als…
Analytical techniques in single and multi-parameter quantum estimation theory: a focused review
Abdallah Slaoui, Lalla Btissam Drissi, El Hassan Saidi +1
As we enter the era of quantum technologies, quantum estimation theory provides an operationally motivating framework for determining high precision devices in modern technological…
On Exceptional 't Hooft Lines in 4D-Chern-Simons Theory
Youssra Boujakhrout, El Hassan Saidi
We study 't Hooft lines and the associated - operators in topological 4D Chern-Simons theory with gauge symmetry given by the exceptional groups E and E. W…
