Non-Markovian super-superradiance in a linear chain of up to 100 qubits
Fatih Dinc, Agata M. Brańczyk · Physical Review Research · 2019
This paper shows how super-superradiance in a waveguide scales with the number of atoms. Usually, superradiance occurs when atoms are separated by distances much smaller than their transition wavelengths, but in waveguide structures, this collective emission phenomenon can persists for even larger periodic separation. Moreover, in a waveguide, this collective decay can become even more superradiant, i.e., super-superradiant. Here, the authors prove that super-superradiance scales linearly with the qubit number, analogous to Dicke superradiance, but with a larger prefactor.
