Subradiance and superradiance-to-subradiance transition in dilute atomic clouds

Diptaranjan Das, B. Lemberger, D. D. Yavuz

We experimentally study subradiance in a dilute cloud of ultracold rubidium (Rb) atoms where $n{\lambda }_a^3\approx 10^{-2}$ ($n$: atomic density, ${\lambda }_a$ excitation wavelength) and the on…
