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…
Coherent backscattering of inelastic photons from atoms and their mirror images
P. H. Moriya, R. F. Shiozaki, R. Celistrino Teixeira +5
Coherent backscattering is a coherence effect in the propagation of waves through disordered media involving two or more scattering events. Here, we report on the observation of co…
Chaos in free electron laser oscillators
C. Bruni, R. Bachelard, D. Garzella +2
The chaotic nature of a storage-ring Free Electron Laser (FEL) is investigated. The derivation of a low embedding dimension for the dynamics allows the low-dimensionality of this c…
