Strong localization of microwaves beyond 2D in aperiodic Vogel spirals
Luis A. Razo-López, Geoffroy J. Aubry, Felipe A. Pinheiro +1
We carry out dynamical microwave transport experiments in aperiodic Vogel spiral arrays of cylinders with high dielectric permittivity. We experimentally disclose the electromagnet…
Low and high-energy localization landscapes for tight-binding Hamiltonians in 2D lattices
Luis A. Razo-López, Geoffroy J. Aubry, Marcel Filoche +1
Localization of electronic wave functions in modern two-dimensional (2D) materials such as graphene can impact drastically their transport and magnetic properties. The recent local…
Experimental Tuning of Transport Regimes in Hyperuniform Disordered Photonic Materials
Geoffroy J. Aubry, Luis S. Froufe-Pérez, Ulrich Kuhl +3
We present wave transport experiments in hyperuniform disordered arrays of cylinders with high dielectric permittivity. Using microwaves, we show that the same material can display…
Topological Effects of a Vorticity Filament on the Coherent Backscattering Cone
Geoffroy J. Aubry, Philippe Roux
In this Letter, we report on the effects of a vorticity filament on the coherent backscattering cone. Using ultrasonic waves in a strongly reverberating cavity, we experimentally s…
Resonant transport and near-field effects in photonic glasses
Geoffroy J. Aubry, Lukas Schertel, Mengdi Chen +5
A fundamental quantity in multiple scattering is the transport mean free path the inverse of which describes the scattering strength of a sample. In this paper, we emphasize the im…
Can 3D light localization be reached in "white paint"?
Tilo Sperling, Lukas Schertel, Mirco Ackermann +3
When waves scatter multiple times in 3D random media, a disorder driven phase transition from diffusion to localization may occur [Anderson 1958 Phys. Rev. 109 1492-505; Abrahams e…
Condensation of helium in aerogels and athermal dynamics of the Random Field Ising Model
Geoffroy Aubry, Fabien Bonnet, Mathieu Melich +4
High resolution measurements reveal that condensation isotherms of He in a silica aerogel become discontinuous below a critical temperature. We show that this behaviour does no…
