Quantum Magnets with Anisotropic Infinite Range Random Interactions
Liliana Arrachea, Marcelo J. Rozenberg
Using exact diagonalization techniques we study the dynamical response of the anisotropic disordered Heisenberg model for systems of S=1/2 spins with infinite range random exchange…
Ion backflow in the Micromegas TPC for the future linear collider
P. Colas, I. Giomataris, V. Lepeltier
We present ion backflow measurements in a Micromegas (MICRO-MEsh GASeous detector) TPC device developed for the next high energy electron-positron linear collider under study and a…
Large deviations for rough paths of the fractional Brownian motion
Annie Millet, Marta Sanz-Solé
Starting from the construction of a geometric rough path associated with a fractional Brownian motion with Hurst parameter given by Coutin and Qian (2002), we…
Radiodetection of Cosmic Ray Extensive Air Showers
D. Ardouin, A. Belletoile, D. Charrier +12
We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
Describing and Simulating Internet Routes
Jeremie Leguay, Matthieu Latapy, Timur Friedman +1
This paper introduces relevant statistics for the description of routes in the internet, seen as a graph at the interface level. Based on the observed properties, we propose and ev…
Extracting clean supernova spectra
S. Blondin, J. R. Walsh, B. Leibundgut +1
We use a new technique to extract the spectrum of a supernova from that of the contaminating background of its host galaxy, and apply it to the specific case of high-redshift Type…
