    Henri Alloul

    Henri Alloul (b, November 4 (1942) in Marrakech, Morocco), completed engineer studies and obtained his B.S in Physics at Ecole Polytechnique, Paris in 1963. Thereafter, he received his Ph.D. in 1968 at the University of Paris-Sud Orsay (now part of Paris-Saclay). He moved on to hold a research assistant position at CNRS, Orsay and after a post-doctoral experience in the Institute of Solid State Physics at Tokyo University, he became research director at CNRS Orsay.

    From 1980 he became involved in teaching as an associate professor in physics in Ecole Polytechnique Palaiseau and then promoted to full professor in 1996, for which he has been awarded a Chevalier des Palmes Académiques medal (2001). He has been named as a Fellow of the American Physical Society (2008) and was awarded the Great Prize of the French Science Academy and CEA Science and Innovation (2012). The Physics department of Kazan Federal University (Russia) has elected him as member of the International Scientific Committee of the university and awarded him a Doctor Honoris Causa diploma (2014) .

    Prof. Alloul has served on the committees of several French and International scientific organizations and has been referee for multiple international scientific journals. He has published ~ 200 scientific papers, given ~100 invited talks at international conferences. He has co-organized 12 summer schools, international conferences or workshops. His lectures at Ecole Polytechnique have been published as a textbook by Springer.

    The main orientation of Prof. Alloul’s research is directed towards understanding the physics of correlated electron systems. His work is mostly experimental and has benefited from the expertise he has acquired over the years on nuclear magnetic resonance techniques. He has also taken advantage from the recent development of a variety of new experimental tools directed towards correlated electron physics in layered materials.

    His main contributions have initially been on Kondo effect, insulating glasses, spin glasses and metal insulator transitions in doped semiconductors. Since the discovery of High Temperature superconductivity H. Alloul has done seminal contributions on the physics of the normal state of these materials and on the incidence of impurities and disorder on their phase diagram. He has also altogether performed detailed studies of the magnetic, superconducting properties and Mott transition in Alkali doped fullerene compounds. NMR/NQR studies allowed him to evidence atomic and charge order phenomena which drive a large variety of original physical properties in Na$_x$CoO$_2$ compounds.

    Each week Scholarpedia recognizes a different contributing author by featuring a short bio of them on the home page.
