Continuity Equation for the Flow of Fisher Information in Wave Scattering
Jakob Hüpfl, Felix Russo, Lukas M. Rachbauer +4
Using waves to explore our environment is a widely used paradigm, ranging from seismology to radar technology, and from bio-medical imaging to precision measurements. In all of the…
Experimental Observation of Multifractality in Fibonacci Chains
Mattis Reisner, Yanel Tahmi, Frédéric Piéchon +2
The tight-binding model for a chain, where the hopping constants follow a Fibonacci sequence, predicts multifractality in the spectrum and wavefunctions. Experimentally, we realize…
Diffuse field cross-correlations: scattering theory and electromagnetic experiments
Matthieu Davy, Philippe Besnier, Philipp del Hougne +7
The passive estimation of impulse responses from ambient noise correlations arouses increasing interest in seismology, acoustics, optics and electromagnetism. Assuming the equipart…
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…
Localisation and transport in bidimensional random models with separable Hamiltonians
Gabino Corona-Patricio, Ulrich Kuhl, Fabrice Mortessagne +2
We consider two bidimensional random models characterised by the following features: a) their Hamiltonians are separable in polar coordinates and b) the random part of the potentia…
Introducing Enhanced Transport to the Effective Hamiltonian Approach via Random Matrices with a Pair of Connecting States
Martin Richter, Fabrice Mortessagne, Olivier Legrand +1
Direct transport processes play an important role in wireless communications where an ideal setup uses microwave fields to establish reliable communication channels between transmi…
