Identification of materials by an advanceded neutronic method.
The EURITRACK inspection system, based on the associated particle technique, aims at detecting explosives and narcotics in cargo containers with 14 MeV neutrons... -
Dynamics and Optical control of a single spin in a Quantum Dot
We have studied the dynamic properties of a single spin (Mn impurity or resident electron) in a II-VI semiconductor quantum dot. A quantum dot doped with a single Mn... -
Nano-patterned silicon surfaces for the self-organised growth of metallic nan...
The aim of this work is to obtain a very regular alignment of metallic nanostructures with high density and a narrow size distribution via a self-organised growth... -

This work deals with the interest in ion beams for controlling nanocrystals synthesis in glasses.<br />We show two different ways to reach this aim, insisting on... -
Theoretical and experimental study of generation and quantum correlations of ...
This work deals about the study of coherence between triple photon beams generated by a third order non linear interaction. A protocol, based on the study of the field... -
Structure, morphology and catalytic activity of gold nanoparticles supported ...
This work focuses on the in operando study of gold NPs supported on TiO2(110) during the CO oxidation reaction. Its goal is the understanding of the catalytic... -
Study of fringe trackers concepts for astrophysical image synthesis. Study of...
Despite its unique ability to discern details that a “classical” instrument cannot see, optical interferometry is still strongly handicapped by the atmosphere. It... -
Absolute luminosity measurements at LHCb
Absolute luminosity measurements are of general interest for colliding-beam experiments at storage rings. These measurements are necessary to determine the absolute... -
