Spin Hall effect in the high-resistivity high-entropy alloy Al-Cr-Mo-W

Jyoti Yadav, Felix Janus, Tiago de Oliveira Schneider, Shalini Sharma, Daniel Schröter, Markus Meinert

<div><p>We study thin films of the high-entropy alloy system Al x (Cr-Mo-W) 1-x , grown on Ta seed layers by magnetron cosputtering. Between x = 0.2 and x = 0.6, a resistivity larger than 100 µ cm is achieved, with a peak of 180 µ cm at x = 0.5. Around the stoichiometric composition Al-…

Automated Planarization of GSG Probes for on-Wafer RF Measurements Using a Nanorobotic Probe Station

Clément Lenoir, Mohamed Sebbache, Gia Ngoc Phung, Kamel Haddadi

This work presents a probe planarization technique for on-wafer ground-signal-ground (GSG) measurements based on a nanorobotic probe station, enabling fully automated and high-precision measurements. The proposed method relies on radio-frequency (RF) measurements of the phase of the reflection…

Superradiance and static Bell tests in pilot-wave hydrodynamics

Konstantinos Papatryfonos, Louis Vervoort, Mélanie Ruelle, Corentin Bourdiol, André Nachbin, Valeri Frumkin, Matthieu Labousse, John W. M. Bush

Since its discovery in 2005, the hydrodynamic pilot-wave system has emerged as a classical platform for exploring aspects of wave–particle duality. In these systems, bouncing droplets or droplets emitted from hydrodynamic cavities propagate on a vertically vibrating fluid bath. These droplets,…

Aerodynamics force estimates from flow field measurements in insect-inspired vibrating wings

Alexandre Dallot, Vincent Stin, Marguerite de La Bigne, Eric Cattan, Sébastien Grondel, Sofiane Ghenna, Olivier Thomas, Benjamin Thiria, Ramiro Godoy-Diana

This study investigates a method to estimate aerodynamic force production of a resonant, twowinged Nano Air Vehicle (NAV) prototype using 2D particle image velocimetry (PIV) and a pressure calculation algorithm. The prototype, with a 7.4 mm chord length, is excited at a range of frequencies around…
