Selective band interaction and long-range hopping in a structured environment with giant atoms
Ying Xia, Jia-Qi Li, Xin Wang
Giant atoms, which couple to the environment at multiple discrete points, exhibit various nontrivial phenomena in quantum optics due to their nonlocal couplings. In this study, we…
