Sensing multiatom networks in cavities via photon-induced excitation resonance
Pritam Chattopadhyay, Avijit Misra, Saikat Sur +2
We explore the distribution in space and time of a single-photon excitation shared by a network of dipole-dipole interacting atoms that are also coupled to a common photonic field…
