However, little is known about its impact from the viewpoint of open quantum systems. Thus, we examine this subject from the perspective of system-environment interactions. We show that the superposition of multiple trajectories can result in quantum state freezing, suggesting a space-time dual to the quantum Zeno effect. Moreover, nontrivial Dicke-like super (sub) radiance can be triggered without utilizing multiatom correlations. Place：F104, Gongguan Campus, NTNU |
