Alexandre Bouzdine
Alexandre Bouzdine (Buzdin) (in Russian - ''Александр Иванович Буздин''; born March 16, 1954) is a French and Russian theoretical physicist in the field of superconductivity and condensed matter physics. He was awarded the Holweck Prize in physics in 2013.
==Biography==
After graduating from the Lomonosov Moscow State University in 1977, Bouzdine received his Ph.D. in 1980 for the theory of magnetic and electronic properties of inhomogeneous systems and then his Doctor of Physical and Mathematical Sciences degree (Habilitation) for a thesis on superconductivity. He worked as a leading scientist at the Institute for High Pressure Physics of the Russian Academy of Science, headed by the future Nobel Prize in Physics Alexei Abrikosov. In addition, Bouzdine became a professor at Moscow State University in 1988.
Since 1996, Alexandre Bouzdine has been working in the University of Bordeaux in France, where he has become a professor of the exceptional class〔:fr:Professeur des universités〕 in 2009. He is a condensed matter physics theory group leader at the Laboratory of Waves and Materials.〔(【引用サイトリンク】title=Laboratoire Ondes et Matière d’Aquitaine )〕〔(【引用サイトリンク】title=Page - ActuDphy )〕 Bouzdine is known for his theoretical contributions into the theory of condensed matter physics, mostly to superconductivity, magnetism and low-dimensional systems. He elaborated a theory of twinning planes' superconductivity, predicted elementary ("pancakes") vortices discovered further on experimentally in layered superconductors. With his colleagues he created a comprehensive description of the Peierls and spin-Peierls transition in magnetic field, predicted the possibility of multi-quanta vortices attached to columnar defects, demonstrated the possibility of tilted vortex attraction in layered superconductors which has received an experimental confirmation. These findings open perspectives for the nano-fabricated superconducting materials and present an important contribution to the general theory of superconductivity .
Bouzdine contributed into the theory of the inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov phase(FFLO) in the superconducting state. In his pioneering theoretical studies of superconductor-ferromagnet (S-F) multilayer systems he found a damped oscillatory behaviour of the superconducting order parameter in the ferromagnetic layer. This unusual S/F proximity effect leads to many interesting phenomena predicted by Bouzdine: the formation of the S-F-S Pi Josephson junction; the oscillations of the density of states with thickness in an F-layer being in contact with a superconductor; the spin-valve effect in F-S-F structures. All these observations are of a major importance for the superconducting spintronics and dynamic interaction between magnetic and superconducting subsystems.
