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…
Phase space anatomy of dynamical quantum phase transitions
Zakaria Mzaouali
Dynamical quantum phase transitions (DQPT) are commonly defined either by the behavior of a late-time order parameter or by nonanalyticities in a quantum state's return rate. We sh…
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…
Thermodynamic significance of QUBO encoding on quantum annealers
Emery Doucet, Zakaria Mzaouali, Reece Robertson +3
Quadratic unconstrained binary optimization (QUBO) is the standard interface to quantum annealers, yet a single constrained task admits many QUBO encodings whose penalty choices re…
EMU circulation planning for Silesian Railways: case study and a quantum approach
Ewa Kędziera, Wojciech Gamon, Mátyás Koniorczyk +3
We study daily rolling stock circulation planning for electric multiple units (EMUs) on a regional passenger network, focusing on services where identical EMUs may be coupled in pa…
