===== Biography =====
Christian GLATTLI, Research Director at CEA,  is born in 1954 and is head of of the Nanoelectronic group at the Service de Physique de l'Etat Condense at the CEA Saclay France. He has also founded the Mesoscopic Physics group at ENS Paris in 2000 (activity from 2000 to 20012)

His main interest are the quantum physics of 2D electron gas using GaAs/GaAlAs and Graphene (Saclay) and of Carbon Nanotube (ENS). After some pionneering work in the field of Electron Crystallisation and of Single Electron Charge effects in 2D Quantum Dots, he has developed new sensitive techniques allowing to perform current fluctuation measurements at very low temperature. He was the first to quantitatively show the quantum shot noise reduction predicted by the scattering model of quantum transport. Then, using current shot noise measurements he provided the first evidence that fractional carriers of charge e/3 do transport the current in the Fractional Quantum Hall Effect (FQHE) regime.

From 2000 to 2011 activities shared between CEA Saclay and ENS Paris turned toward the study of quantum noise and quantum transport at very high frequencies. Among recent results in quantum Shot noise are: the observation of photo-assisted electron-hole pairs quantum partition noise (Saclay), the high frequency shot noise of a Quantum Point Contact (Saclay), the study of the quantum statistics of photon emitted by a conductor using an original Hanbury-Brown Twiss experiment at 20mK (Saclay +Paris), the quantum statistics of photons emitted by a tunnel junction (Saclay) and the shot noise suppresion in a Carbon Nanotube (ENS Paris). Regarding high fequency transport:  the first measurement of the quantum charge relaxation of a mesoscopic capacitor (ENS Paris) and the realisation of an on-demand single electron source opening the way for quantum information with electrons (ENS Paris).

Since 2008 he has  developped the new project on Mesoscopic Quantum Noise funded by an ERC Advanced Grant from the European Research Council, to study the Full Counting Satistics of few electrons or fractional charges injected in a coherent conductors and to realize a new type of photon detectors based on photo-assisted shot noise up to THz frequency. Recent results (>2012) include  Graphene plasmonics, a new on-demand single electron source based on Levitons and the first Quantum State Tomography of an electron.
