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…
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…
Charge disproportionation driven polar magnetic metallic double-layered perovskite SrCoO
Hong-Fei Huang, Houssam Sabri, Jiadong Zang +1
Strong coupling among spontaneous structural symmetric breaking, magnetism and metallicity in an intrinsic polar magnetic metal can give rise to novel physical phenomena and holds…
Topological Hall-like behavior of multidomain ferromagnets
Houssam Sabri, Benjamin E. Carlson, Sergey S. Pershoguba +1
We investigate the emergence of topological Hall-like (THE-like) signals in disordered multidomain ferromagnets. Non-monotonic behavior in Hall resistivity, commonly attributed to…
