Acoustic flat lensing using an indefinite medium
M. Dubois, J. Perchoux, A. L. Vanel +10
Acoustic flat lensing is achieved here by tuning a phononic array to have indefinite medium behaviour in a narrow frequency spectral region along the acoustic branch. This is confi…
Lamb shift multipolar analysis
Emmanuel Lassalle, Alexis Devilez, Nicolas Bonod +2
It is now well established that radiative decay of quantum emitters can be strongly modified by their environment. In this paper we present an exact, within the weak-coupling appro…
Conditions for anti-Zeno effect observation in free-space atomic radiative decay
Emmanuel Lassalle, Caroline Champenois, Brian Stout +2
Frequent measurements can modify the decay of an unstable quantum state with respect to the free dynamics given by Fermi's golden rule. In a landmark article, Nature 405, 546 (2000…
Approached vectorial model for Fano resonances in guided mode resonance gratings
Anne-Laure Fehrembach, Boris Gralak, Anne Sentenac
We propose a self-consistent vectorial method, based on a Green's function technique, to describe the Fano resonances that appear in guided mode resonance gratings. The model provi…
Dykes for filtering ocean waves using c-shaped vertical cylinders
Guillaume Dupont, Fabien Remy, Olivier Kimmoun +3
The present study investigates a way to design dykes which can filter the wavelengths of ocean surface waves. This offers the possibility to achieve a structure that can attenuate…
Bio-inspired seismic metamaterials: Time domain simulations in transformed crystals
Ronald Aznavourian, Tania Puvirajesinghe, Stephane Brule +2
We introduce the concept of transformation crystallography which consists of the application of geometric transforms to periodic structures. We consider motifs with three-fold, fou…
