Report of International NanoSPD Steering Committee and statistics on recent NanoSPD activities
The Université de Lorraine in Metz, France, is the selected site for the 6th International Conference on Nanomaterials by Severe Plastic Deformation (NanoSPD6) following a series of five earlier conferences. This introductory paper reports on several major developments in NanoSPD activities as well as on very recent NanoSPD citation data which confirm the continued growth and expansion of this important research area. Close attention is given to the topics of workshops, conferences and seminars organized during these last three years as well as on books and reviews published prior to the NanoSPD6 conference. A special concern of the committee is in introducing and discussing the appropriate terminology to be applied in this new field of materials science and engineerin
Single-Particle Properties from Kohn-Sham Green's Functions
An effective action approach to Kohn-Sham density functional theory is used
to illustrate how the exact Green's function can be calculated in terms of the
Kohn-Sham Green's function. An example based on Skyrme energy functionals shows
that single-particle Kohn-Sham spectra can be improved by adding sources used
to construct the energy functional.Comment: 9 pages, 3 figure
Nuclear magnetic resonance spectrum of 31P donors in silicon quantum computer
The influence of the electric field created by a gate potential of the
silicon quantum computer on the hyperfine interaction constant (HIC) is
obtained. The errors due to technological inaccuracy of location of donor atoms
under a gate are evaluated. The energy spectra of electron-nuclear spin system
of two interacting donor atoms with various values of HIC are calculated. The
presence of two pairs of anticrossing levels in the ground electronic state is
shown. Parameters of the structure at which errors rate can be greatly
minimized are found.Comment: 12 pages,, 3 figure
