A machine learning architecture for including wave breaking in envelope-type wave models
Wave breaking is a complex physical process about which open questions remain. For some applications, it is critical to include breaking effects in phase-resolved envelope-based wave models such as the non-linear Schr & ouml;dinger. A promising approach is ...
Pergamon-Elsevier Science Ltd2024Collective motion in a sheet of microswimmers
Self-propelled particles such as bacteria or algae swimming through a fluid are non-equilibrium systems where particle motility breaks microscopic detailed balance, often resulting in large-scale collective motion. Previous theoretical work has identified ...
Berlin2024Non-contact robotic manipulation of floating objects: exploiting emergent limit cycles
Josephine Anna Eleanor Hughes, Nana Obayashi
The study of non-contact manipulation in water, and the ability to robotically control floating objects has gained recent attention due to wide-ranging potential applications, including the analysis of plastic pollution in the oceans and the optimization o ...
Lausanne2023Improving the radiation characteristics of shorted annular ring antennas through symmetric aperture-coupled feeding
Anja Skrivervik, Hannes Bartle
In this paper, a novel feeding method for shorted annular ring (SAR) antennas is presented. SAR antennas can be designed to not excite surface waves and hence have desirable properties for many applications. The traditional method of feeding a SAR is throu ...
IEEE2023Stochastic particle transport by deep-water irregular breaking waves
Correct prediction of particle transport by surface waves is crucial in many practical applications such as search and rescue or salvage operations and pollution tracking and clean-up efforts. Recent results by Deike et al. (J. Fluid Mech., vol. 829, 2017, ...
Cambridge2023Nonlinear interactions of ion acoustic waves explored using fast imaging decompositions
Fast camera imaging is used to study ion acoustic waves propagating azimuthally in a magnetized plasma column. The high-speed image sequences are analyzed using proper orthogonal decomposition and 2D Fourier transform, allowing to evaluate the assets and d ...
AIP Publishing2023Natural slicks on Lake Geneva: From small-scale effects to large-scale formation and distribution
Low wind speeds (< 4 m/s) are ubiquitous in many water bodies, yet the physical processes occurring at the air-water interface in this range are poorly understood. A notable example is smooth patches on the water surface, known as natural slicks, formed wh ...
EPFL2023Optimization of elastic wave propagation in a reconfigurable medium by genetic algorithms with adaptive mutation probability
Romain Christophe Rémy Fleury, Janez Rus
We introduce a reconfigurable medium for the manipulation of elastic propagation properties of Lamb waves. It is based on a shape memory polymer (SMP) with temperature-dependent Young's modulus. Waves are excited by a laser pulse and detected by a laser vi ...
IOP Publishing Ltd2023Density-wave ordering in a unitary Fermi gas with photon-mediated interactions
Jean-Philippe Brantut, Timo Zwettler, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi, Elvia Colella
A density wave (DW) is a fundamental type of long-range order in quantum matter tied to self-organization into a crystalline structure. The interplay of DW order with superfluidity can lead to complex scenarios that pose a great challenge to theoretical an ...
