The very low temperature properties of two pyrochlore compounds, Yb2Ti2O7 and Gd2Sn2O7, were investigated using an ensemble of microscopic and bulk techniques. In both compounds, a first order transition is evidenced, as well as spin dynamics persisting do ...
A simple 0D analytical model for the prediction of the take-off point observed in critical-current or current-sharing tests in cable-in-conduit conductors (CICC) is presented. This may be referred to also as the quench point and defined as the point where ...
The dynamic response of two-dimensional Josephson junction arrays close to, but above the Berezinskii-Kosterlitz-Thouless (BKT) transition temperature is described in terms of the vortex dielectric function ε(ω) and the flux noise spectrum S φ (ω). They ar ...
Optimistic atomic broadcast: a pragmatic viewpoint F.Pedone and A.Schiper This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total-order property experienced in local-area networks in order to allow fa ...
The dynamics of resonant Rayleigh scattering (RRS) from excitons localized in a disorder potential with large monolayer islands is investigated theoretically and experimentally. Experimentally, the coherent RRS dynamics from GaAs single quantum wells (SQWs ...
We consider a design approach to reduce unwanted zero-order intensity due to profile depth error in diffractive elements. Our method is based on addition of local bias phase to a binary element phase, leading to the introduction of a third phase level. We ...
We introduce an atomistic model structure of the Si(1 0 0)-SiO2 interface which incorporates atomic-scale information from a variety of experimental probes. The interface model consists of a disordered, topologically perfect oxide network matching the Si s ...
High-resolution transmission electron microscopy (HRTEM) and HRTEM simulation by the Bloch wave method (JEMS) are used to determine the structure and thickness of micro- and nanocrystals of biominerals and hydroxyapatite grown from aqueous solutions. It is ...
We show how high-resolution NMR spectra can be obtained for solids for which the spectra are normally broadened due to structural disorder. The method relies on correlations in the chemical shifts between pairs of coupled spins. It is found experimentally ...
This work is devoted to the study of the analyticity properties of thermodynamic potentials (free energy, pressure) for classical lattice systems at low temperature. The central topic of our analysis, in this framework, is to show rigorously the absence of ...
