Physics of Quantum Rings (eBook)

Vladimir M. Fomin is a Research Professor at the Institute for Integrative Nanosciences (IIN), Leibniz Institute for Solid State and Materials Research (IFW) Dresden and a Professor of Theoretical Physics at the State University of Moldova. He received his Ph.D. in Theoretical Physics from the State University of Moldova in 1978. His research pertained to non-linear optical properties and transport in semiconductors and multi-layer structures. He was awarded the State Prize of Moldova in 1987, and received his degree of Doctor of physical and mathematical sciences (“habilitation”, Academy of Sciences of Moldova) in 1990. Since 1995 he has been a Professor of Theoretical Physics at the State University of Moldova. In 1999, he received a Diploma of a Scientific Discovery of the Phenomenon of the Propagation of Spatially-Extended Interface Phonon Polaritons in Composite Superlattices from the Academy of Natural Sciences of Russia. He was a Research Fellow of the Alexander von Humboldt Foundation (Martin-Luther-University of Halle, 1993-1994), University of Antwerp, 1995-2008 and Eindhoven University of Technology, 1998-1999 and 2003-2007, Catholic University of Leuven, 2008, University of Duisburg-Essen, 2008-2009, and the IIN IFW Dresden since 2009. In 2007 he became an Honorary Member of the Academy of Sciences of Moldova. His scientific interests currently concern topology- and geometry-driven phenomena in nanophysics, especially the physics of quantum rings. He has published four books and over 200 scientific articles, and holds 10 patents.
