Single-photon superradiant emission rate scaling for atoms trapped in a photonic waveguide
Yao Zhou, Zihao Chen, Jung‐Tsung Shen · Physical Review A · 2017
A recent experiment reveals the linear scaling property of the superradiant emission rate for a trapped atom cloud that is excited by weak and short light pulses. We adopt a real-space approach to numerically demonstrate that such a linear scaling law can be interpreted as single-photon superradiance, in both the time domain and the frequency domain. The dependence of the single-photon superradiant emission rate on the distance between atoms is investigated. We further study the single-photon superradiance for artificial atoms that have deviations in transition frequencies and decay rates.
