Experimental Observation of the Spectral Gap in Microwave n-Disk Systems

S. Barkhofen, T. Weich, A. Potzuweit +3

Symmetry reduced three-disk and five-disk systems are studied in a microwave setup. Using harmonic inversion the distribution of the imaginary parts of the resonances is determined…

Half-integer Mott-insulator phases in the imbalanced honeycomb lattice

Krzysztof Gawryluk, Christian Miniatura, Benoît Grémaud

Using mean-field theory, we investigate the ground state properties of ultracold bosons loaded in a honeycomb lattice with on-site repulsive interactions and imbalanced nearest-nei…

Coherent and Incoherent Multiple Scattering

Julien Chabe, Mohamed-Taha Rouabah, Louis Bellando +4

We compare two different models of transport of light in a disordered system with a spherical Gaussian distribution of scatterers. A coupled dipole model, keeping into account all…

Topological transition of Dirac points in a microwave experiment

Matthieu Bellec, Ulrich Kuhl, Gilles Montambaux +1

By means of a microwave tight-binding analogue experiment of a graphene-like lattice, we observe a topological transition between a phase with a point-like band gap characteristic…

Steady-state signatures of radiation trapping by cold multilevel atoms

Quentin Baudouin, Nicolas Mercadier, Robin Kaiser

In this paper, we use steady-state measurements to obtain evidence of radiation trapping in an optically thick a cloud of cold rubidium atoms. We investigate the fluorescence prope…

Cross time-bin photonic entanglement for quantum key distribution

A. Martin, F. Kaiser, A. Vernier +3

We report a fully fibered source emitting cross time-bin entangled photons at 1540 nm from type-II spontaneous parametric down conversion. Compared to standard time-bin entanglemen…
