Deviations from thermal light statistics in ensembles of independent two-level emitters
Manuel Bojer, André Cidrim, Romain Bachelard +1
We investigate the light statistics of an ensemble of independent motionless two-level atoms in a product state. We identify the conditions under which the cold atomic ensemble emi…
Coherent Control of Photon Correlations in Trapped Ion Crystals
K. Singh, A. Cidrim, A. Kovalenko +4
While the spontaneous emission from independent emitters provides spatially uncorrelated photons - a typical manifestation of quantum randomness, the interference of the coherent s…
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…
