Time localization of energy in disordered time-modulated systems
Benjamin Apffel, Sander Wildeman, Antonin Eddi +1
Wave localization induced by spatial disorder is ubiquitous in physics. Here, we study the temporal analog of such phenomenon on water waves. Our time disordered media consists in…
Slingshot droplet generator for clogging-free and tunable production of small uniform drops in air
K. S. Surabhi, Sander Wildeman
Submillimeter air-borne drops of well defined size are notoriously difficult to produce in the lab. Here, we demonstrate that any simple droplet dripper, in which millimetric dropl…
Dynamics of heavy and buoyant underwater pendulums
Varghese Mathai, Laura Loeffen, Timothy Chan +1
The humble pendulum is often invoked as the archetype of a simple, gravity driven, oscillator. Under ideal circumstances, the oscillation frequency of the pendulum is independent o…
Observation of the Talbot effect with water waves
Alexandra Bakman, Shmuel Fishman, Mathias Fink +2
When light is incident upon a diffraction grating, images of the grating appear at periodic intervals behind the grating. This phenomenon and the associated self-imaging distance w…
Real-time quantitative Schlieren imaging by fast Fourier demodulation of a checkered backdrop
Sander Wildeman
A quantitative synthetic Schlieren imaging (SSI) method based on fast Fourier demodulation is presented. Instead of a random dot pattern (as usually employed in SSI), a 2D periodic…
Classical analogue of the Unruh effect
Ulf Leonhardt, Itay Griniasty, Sander Wildeman +2
In the Unruh effect an observer with constant acceleration perceives the quantum vacuum as thermal radiation. The Unruh effect has been believed to be a pure quantum phenomenon, bu…
