Postselected Entangled States by Photon Detection
Pedro Rosario, A. Cidrim, R. Bachelard
Postselection is a non-deterministic mechanism to entangle subsystems, often used in weakly-excited systems. We here show how highly-excited ensembles of two-level emitters can be…

Unraveling Dicke Superradiant Decay with Separable Coherent Spin States
Pedro Rosario, Luiz O. R. Solak, A. Cidrim +2
We show that idealized Dicke superradiant decay from a fully inverted state can at all times be described by a positive statistical mixture of coherent spin states (CSS). Since CSS…

Light Statistics from Large Ensembles of Independent Two-level Emitters: Classical or Non-classical?
M. Bojer, A. Cidrim, P. P. Abrantes +2
We investigate the photon statistics of an ensemble of coherently driven non-interacting two-level atoms in the weak driving regime. As it turns out, the system displays unique emi…
