Topological protection of electronic states against disorder probed by their magnetic moment

Athmane Tadjine, Christophe Delerue

Magnetic moments (MMs) of electrons in topological insulator quantum dots (TI-QDs) are investigated using a model system, namely a multiorbital honeycomb lattice. Their nature and orientation with respect to the spin are studied. We show that large MMs are not specific to edge states in nontrivial...

Separation of two fractions of immiscible liquids by ultrasound in microgravity

Leonid Krutyansky, Farzam Zoueshtiagh, Philippe Pernod, P. Shirkovskiy, Andrey Brysev

Ultrasonic separation of two immiscible liquids under microgravity conditions has been demonstrated on example of liquid mixtures of FC-70 or FC-72 with silicone oils of 1.5 or 1.0 cSt viscosities, respectively. A 3-MHz focused ultrasound beam was utilized to form an emulsion from these liquid...

Supramolecular self-assembly on the B-Si(111)-(√3x√3) R30° surface: From single molecules to multicomponent networks

Younes Makoudi, Judicaël Jeannoutot, Frank Palmino, Frédéric Cherioux, Guillaume Copie, Christophe Krzeminski, Fabrizio Cleri, B. Grandidier

Understanding the physical and chemical processes in which local interactions lead to ordered structuresis of particular relevance to the realization of supramolecular architectures on surfaces. While spectacularpatterns have been demonstrated on metal surfaces, there have been fewer studies of the...

Near-Field Scanning Millimeter-wave Microscope Combined with a Scanning Electron Microscope

Gilles Dambrine, Kamel Haddadi, Olaf C. Haenssler, Christophe Boyaval, Didier Theron

The design, fabrication and experimental validation of a novel near-field scanning millimeter-wave microscope (NSMM) built inside a scanning electron microscope (SEM) is presented. The instrument developed can perform hybrid characterizations by providing simultaneously atomic force, complex...

Evaluation of the Impact of Transient Disturbances on Railway Signaling Systems Using an Adapted Time-Frequency Analysis Method

Mohamed Raouf Kousri, Virginie Deniau, Marc Heddebaut, S. Baranowski

As many other industrial environments, the railway electromagnetic environment is characterized by a large number of electromagnetic signals and disturbances. Among these, transient signals, with high energy level and wide frequency spectrum, represent an important threat to different signaling..., Comme beaucoup d'autres environnements industriels, l'environnement électromagnétique ferroviaire est caractérisé par un grand nombre de signaux électromagnétiques et de perturbations. Parmi ceux-ci, les signaux transitoires, avec un niveau d'énergie élevé et un large spectre de...

Interaction between Cr-bearing pigments and transparent glaze: A transmission electron microscopy study

Louisiane Verger, Olivier Dargaud, Nicolas Menguy, David Troadec, Laurent Cormier

Spinel ZnAl2O4 and corundum Al2O3 doped with chromium are used as pink pigments in porcelain glazes. However, alteration of the color can occur during firing, and the resulting glaze appears brown and green respectively, instead of the expected pink. To investigate the mechanism of color change,...
