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…
