Spontaneous Emission from Electronic Metastable Resonance States
Author(s): Amir Sivan, Milan Šindelka, Meir Orenstein, and Nimrod Moiseyev
We demonstrate that calculating the spontaneous emission decay rate from metastable resonance states (states with finite lifetimes embedded in the continuum) requires considering transitions to all continuum states, not just to lower states. This holds even when the lifetimes of the metastable state… [Phys. Rev. Lett. 135, 163001] Published Tue Oct 14, 2025
