Micro-mechanical modelling of alkali-silica-reaction-induced degradation using the AMIE framework

AMIE. a finite element/extended finite element framework, has been designed to provide the tools to run detailed microstructural simulations; this paper demonstrates the possibility of simulating the mechanisms underlying the alkali-silica-reaction (ASR). ...

Re-examining the directional-ordering transition in the compass model with screw-periodic boundary conditions

Sandro Wenzel

We study the directional-ordering transition in the two-dimensional classical and quantum compass models on the square lattice by means of Monte Carlo simulations. An improved algorithm is presented which builds on the Wolff cluster algorithm in one-dimens ...

Cavity Optomechanics with Whispering-Gallery Mode Optical Micro-Resonators

Tobias Kippenberg, Albert Schliesser

Parametric coupling of optical and mechanical degrees of freedom forms the basis of many ultra-sensitive measurements of both force and mechanical displacement. An optical cavity with a mechanically compliant boundary enhances the optomechanical interactio ...

Study of an octahedral antenna for both sound pressure level estimation and 3D localization of multiple sources

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

This study deals with localization and characterization of multiple sources by mean of an octahedral array processing. We show how correlations enable to both localize more sources that the number of sensors and estimate their sound level pressure simultan ...

Topography and work function measurements of thin MgO(001) films on Ag(001) by nc-AFM and KPFM

Marina Pivetta

The surface topography and local surface work function of ultrathin MgO(001) films on Ag(001) have been studied by noncontact atomic force microscopy (nc-AFM) and Kelvin probe force microscopy (KPFM). First principles calculations have been used to explain ...

TRANSVERSE MODE COUPLING INSTABILITY MEASUREMENTS AT TRANSITION CROSSING IN THE CERN PS

Sandra Aumon

Transition crossing in the CERN PS is critical for the stability of high intensity beams, even with the use of a second order gamma jump scheme. The intense single bunch beam used for the neutron Time-of-Flight facility (n-ToF) needs a controlled longitudi ...

Optical properties of clusters and molecules from real-time time-dependent density functional theory using a self-consistent field

Efthimios Kaxiras, Sheng Meng, Jun Ren

We present a detailed study of optical absorption spectra of finite-size structures, using a method based on time-dependent density-functional theory (TDDFT), which involves a self-consistent field for the propagation of the Kohn-Sham wavefunctions in real ...

Experimental investigation of fast ion dynamics in TORPEX toroidal plasmas

Boris Roulet

The goal of the present diploma work is to experimentally investigate the fast ion physics in TORPEX plasmas, in which interchange modes with flute characteristics and intermittent transport events, i.e. blobs, are observed to dominate the plasma dynamics. ...

Resolved-sideband cooling and position measurement of a micromechanical oscillator close to the Heisenberg uncertainty limit

Tobias Kippenberg, Albert Schliesser

The theory of quantum measurement of mechanical motion, describing the mutual coupling of a meter and a measured object, predicts a variety of phenomena such as quantum backaction, quantum correlations and non-classical states of motion. In spite of great ...

Quantum Yield Measurement of Fluorescent Zeolite Nanopigments

Libero Zuppiroli, Rolando Ferrini

Organic fluorescent molecules are infiltrated in the channels of zeolite L nanocrystals, thus creating organic-inorganic fluorescent nanoparticles. Combined with dielectric matrices, these fluorescent nanopigments open the way to the realization of novel o ...
