Decoupling ultrastrong Rabi splitting from quantum vacuum dressing in a chiral cavity
Ayoub El-Amrani, Nasir Boubekraoui, Zakaria Mzaouali +4
Polariton formation and quantum vacuum dressing are usually regarded as intertwined consequences of ultrastrong light--matter coupling. Here we show that they can be selectively co…

Tunable Electron Quantum Optics in Graphene Slit Junctions
Mohamed Amine Rhanbouri, Wojciech Julian Pasek, Abdelouahed El Fatimy
A graphene slit junction is investigated as a compact geometry for directional electron-beam formation, coherent interference, and symmetry-controlled spin filtering. Atomistic tig…

Chirality routing non-polaritonic vacuum correlations in Landau polaritons
Ayoub EL-Amrani, Zakaria Mzaouali, Houssam Sabri +3
Ultrastrong coupling between matter and cavity vacuum fields can turn the electromagnetic vacuum into a structured quantum environment, thereby opening passive routes for modifying…
