Dressed Interference in Giant Superatoms: Entanglement Generation and Transfer
Lei Du, Xin Wang, Anton Frisk Kockum +1
We introduce the concept of giant superatoms (GSAs), where two or more interacting atoms are nonlocally coupled to a waveguide through one of them, and explore their unconventional…
