Phase-switchable nonreciprocal entanglement via magnon squeezing in ring-cavity optomagnomechanics
Z. Imara, A. El Allati, A. Belfakir +2
Cavity optomagnomechanics provides a versatile platform to explore macroscopic quantum correlations, particularly nonreciprocal entanglement. In this work, we propose a theoretical…

Exploring vibronic dynamics near a sloped conical intersection with trapped Rydberg ions
Abdessamad Belfakir, Weibin Li
We study spin-phonon coupled dynamics in the vicinity of a sloped conical intersection created by laser coupling the electronic (spin) and vibrational degrees of freedom of a pair…

Directional Motional Control via Engineered Conical Intersections in Trapped Rydberg Ions
Abdessamad Belfakir, Yousra Bouasria, Herschel Rabitz +1
We demonstrate coherent control of motional dynamics in trapped Rydberg ions engineered to exhibit a conical intersection between adiabatic potential-energy surfaces. Using quantum…
