Spinon deconfinement in doped frustrated quantum antiferromagnets

The confinement of a spinon liberated by doping two-dimensional frustrated quantum antiferromagnets with a nonmagnetic impurity or a mobile hole is investigated. For a static vacancy, an intermediate behavior between complete deconfinement (kagome) and str ...

A 2-DOF fMRI Compatible Haptic Interface to Interact with Arm Movements

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet, Olivier Lambercy, Ludovic Dovat, Yves Ruffieux

This paper describes a two-degrees-of-freedom haptic interface to investigate the brain mechanisms of human motor control, which is capable of safely and gently interacting with human arm motion during functional magnetic resonance imaging (fMRI). A hydros ...

Probing the validity of the Derjaguin approximation for heterogeneous colloidal particles

Ramon Pericet Camara, Michal Borkovec

The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...

Leptogenesis beyond the limit of hierarchical heavy neutrino masses

Steve Blanchet

We calculate the baryon asymmetry of the Universe in thermal leptogenesis beyond the usual lightest right-handed (RH) neutrino dominated scenario (N_1DS) and in particular beyond the hierarchical limit (HL), M_1 < M_2 < M_3, for the RH neutrino mass spec ...

Etude physique de l'apparition et du développement de la cavitation sur une aube isolée

Mohamed Faiçal Guennoun

The physical mechanism that governs the incipience and development of leading edge cavitation on hydrofoils is still not fully understood. It involves several parameters such as the pressure level, the nuclei content, the surface roughness and the boundary ...

Interaction forces between surfaces coated with highly branched polyelectrolytes

Ramon Pericet Camara

In this thesis, interactions between surfaces with adsorbed highly branched polyelectrolytes were studied with the colloidal probe technique. By studying the adsorption behavior of highly branched polyelectrolytes, the lateral distribution of the surface c ...

Awareness: An Enabling Feature for mediated Interaction in Communities of Practise

Denis Gillet, Christophe Salzmann

The École Polytechnique Fédérale de Lausanne (EPFL) is currently using a Web-based experimentation environment to support laboratory activities in engineering education. The key service for the acceptance of the learning modalities and the appropriation of ...

Photoluminescence characterization of localized 2D-layers of few-nanocrystals electronic devices

Marc Antonius Friedrich van den Boogaart

Photoluminescence (PL) spectroscopy has been demonstrated as a suitable technique to characterize Si nanocrystal-based non-volatile memory devices (Carrada et al. APL 2005). These are formed by a single plane of Si nanocrystals (NCs) buried in the gate oxi ...

Interaction forces and molecular adhesion between pre-adsorbed poly(ethylene imine) layers

Ramon Pericet Camara, Michal Borkovec

Interaction forces between pre-adsorbed layers of branched poly(ethylene imine) (PEI) of different molecular mass were studied with the colloidal probe technique, which is based on atomic force microscopy (AFM). During approach, the long-ranged forces betw ...

Micromechanical finite element modeling of compressive fracture in confined alumina ceramic

Jean-François Molinari, Derek Warner

A two-dimensional finite element model is developed to investigate intergranular fracture in alumina under compression. The grain interiors are modeled as anisottopic elastic and the properties of the grain boundaries are fitted from experimental data. Mat ...
