Quantitative measurement of the thermal contact resistance between a glass microsphere and a plate
Joris Doumouro, Elodie Perros, Alix Dodu +6
Accurate measurements of the thermal resistance between micro-objects made of insulating materials are complex because of their small size, low conductivity, and the presence of va…
Non-destructive characterisation of dopant spatial distribution in cuprate superconductors
A. -E. Tutueanu, M. Sales, K. L. Eliasen +9
Proper characterisation of investigated samples is vital when studying superconductivity as impurities and doping inhomogeneities can affect the physical properties of the measured…
Positron production using a 9 MeV electron linac for the GBAR experiment
M. Charlton, J. J. Choi, M. Chung +67
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses…
Structure-Composition Correspondence in Crystalline Metamaterials for Acoustic Valley-Hall Effect and Unidirectional Sound Guiding
Simon Yves, Geoffroy Lerosey. Fabrice Lemoult
Recently, the domain of topological insulators in condensed matter physics has been teeming with intriguing and very exciting discoveries. Notably, the capacity of guiding currents…
Light control of the diffusion coefficient of active fluids
Thomas Vourc'h, Julien Léopoldès, Hassan Peerhossaini
Active fluids refer to the fluids that contain self-propelled particles such as bacteria or micro-algae, whose properties differ fundamentally from the passive fluids. Such particl…
Clustering of bacteria with heterogeneous motility
Thomas Vourc'h, Julien Léopoldès, Hassan Peerhossaini
We study the clustering of a model cyanobacterium \textit{Synechocystis} into microcolonies. The bacteria are allowed to diffuse onto surfaces of different hardness, and interact w…
