Strong Collective Chiroptical Response from Electric-Dipole Interactions in Atomic Systems
Marcella L. Xavier, Felipe A. Pinheiro, Romain Bachelard
Chiroptical responses in atomic systems are usually weak, as they arise from the interference between electric- and much weaker magnetic-dipole transitions. We show that atoms arra…

Engineering Atom-Photon Hybridization with Density-Modulated Atomic Ensembles in Coupled Cavities
Carlos E. Máximo, Romain Bachelard, Tobias Donner
Radiation-matter hybridization allows atoms to serve as mediators of effective interactions between light modes and, conversely, to interact among themselves via light. Here we exp…

Breaking of reciprocity and the Pancharatnam-Berry phase for light scattered by a disordered cold atom cloud
P. H. N. Magnani, P. G. S. Dias, M. Frometa +7
Collective effects on the light scattered by disordered media such as Anderson localization and coherent backscattering critically depend on the reciprocity between interfering opt…
