Polarization-controlled transport of light in a two-dimensional waveguide
J. V. S. Ferreira, A. M. G de Melo, N. A. Moreira +3
Light propagation in disordered media is particularly complex due to the interference effects and polarization-mixing terms. Two-dimensional systems are particularly interesting be…
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…
Detecting multilevel entanglement from light-based entanglement witnesses
Pedro Rosario, Romain Bachelard
We introduce a set of electric-field based inequalities capable of detecting multilevel entanglement from a system of N quantum emitters. We determine that the polarization channel…
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…
Nonergodic extended phase for waves in three dimensions
Marcus Prado, Romain Bachelard, Robin Kaiser +1
Wave transport in complex media is determined by the nature of quasimodes at the microscopic level. In three dimensional disordered media, waves generally undergo a phase transitio…
