Microscopic quantum description of surface plasmon polaritons: Revealing intrinsic ultrastrong light-matter coupling
Florian Maurer, Thomas F. Allard, Yanko Todorov +2
We develop a microscopic quantum theory of surface plasmon polaritons valid for arbitrary metal-dielectric geometries. Our framework is based on the Power-Zienau-Woolley representa…
A diffusion model for light scattering in ejecta
J. A. Don Jayamanne, J. -R. Burie, O. Durand +2
We derive a diffusion equation for light scattering from ejecta produced by extreme shocks on metallic samples. This model is easier to handle than a more conventional model based…
Harnessing coherent-wave control for sensing applications
Pablo Jara, Arthur Goetschy, Hui Cao +1
Imaging techniques such as functional near-infrared spectroscopy (fNIRS) and diffuse optical tomography (DOT) achieve deep, non-invasive sensing in turbid media, but they are const…
Theoretical predictions for ultrasensitive sensing in three-dimensional stochastic interferometry
Guillaume Graciani, Marcel Filoche
We show that a random light field can be harnessed for high-precision metrology by introducing specific boundary conditions in the form of Lambertian reflections inside a cavity. W…
Analog phase-sensitive time-reversal of optically-carried radiofrequency signals
Thomas Llauze, Anne Louchet-Chauvet
Achieving low-latency time-reversal of broadband radiofrequency signals is crucial for reliable communications in dynamic, uncontrolled environments. However, existing approaches a…
Causality and instability in wave propagation in random time-varying media
Romain Pierrat, Julia Rocha, Rémi Carminati
We develop a theoretical model to investigate wave propagation in media with random time-varying properties, where temporal fluctuations lead to complex scattering dynamics. Focusi…
