Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

The transition from sticking to sliding of frictional interfaces is a phenomenon of importance for many physical systems in nature as well as in engineering. This transition is marked by the occurrence of local slip events, often called precursors, which a ...

Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors and Rupture Velocity

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Vladislav Yastrebov

The rupture dynamics of earthquakes span a considerable range, from slow to super-shear ruptures. Rupture speed has a major influence on the generation of strong ground motions, yet our understanding of the mechanisms causing these variations in the ruptur ...

We review the details of domain wall (DW) propagation due to spin-polarized currents that could potentially be used in magnetic data storage devices based on domains and DWs. We discuss briefly the basics of the underlying spin torque effect and show how t ...

Thermal Spin Transfer Torque and Transverse Spin Relaxation in Spin Valves

Haiming Yu

Spin caloritronics, i.e., the addition of thermal effects to the electrical and magnetic properties of nanostructures, has recently seen a rapid development. It has been predicted that a heat current can exert a spin torque on the magnetization in a nanost ...

Augmented White Cane with Multimodal Haptic Feedback

Hannes Bleuler, Dominique Chapuis, Simon Gallo, Roger Gassert, Laura Santos Carreras

This paper proposes an instrumented handle with multimodal augmented haptic feedback, which can be integrated into a conventional white cane to extend the haptic exploration range of visually impaired users. The information extracted from the environment t ...

We developed a non-lithographic technique to contact sub-100 nm nanowires for spin transfer torque experiments. Co/Cu multilayers were grown by electrodeposition in nanoporous commercial polycarbonate membranes from a Co/Cu bath. A home-made sample holder ...

Spintronics: Conceptual Building Blocks

Jean-Philippe Ansermet

The purpose of this introduction to spintronics is to provide some elementary description of its conceptual building blocks. Thus, it is intended for a newcomer to the field. After recalling rudimentary descriptions of spin precession and spin relaxation, ...

Springer-Verlag New York, Ms Ingrid Cunningham, 175 Fifth Ave, New York, Ny 10010 Usa2010

Using a homodyne detection scheme, we show that we can determine the polarity and chirality of a magnetic vortex in an asymmetric magnetic disk as well as the resonance frequency and phase shift of the dynamic vortex gyration excited by a spin-polarized cu ...

This article is devoted to the study of an incompressible viscous flow of a fluid partly enclosed in a cylindrical container with an open top Surface and driven by the constant rotation of the bottom wall. Such type of flows belongs to a group of recircula ...

Emergent semantics

Philippe Cudré-Mauroux

In the past, the problem of semantic interoperability in information systems was mostly solved by means of centralization, both at a system and at a logical level. This approach has been successful to a certain extent, but offers limited scalability and fl ...
