On an atomic decomposition in Banach spaces
An atomic decomposition is considered in Banach space. A method for constructing an atomic decomposition of Banach space, starting with atomic decomposition of subspaces is presented. Some relations between them are established. The proposed method is used in the study of the frame properties of systems of eigenfunctions and associated functions of discontinuous differential operators.
متن کاملIndentation-formed nanocontacts: an atomic-scale perspective.
One-to-one comparisons between indentation experiments and atomistic modelling have until recently been hampered by the discrepancy in length scales of the two approaches. Here, we review progress in atomic-scale nanoindentation experiments employing scanning probe techniques to achieve depth-sensing indentation and field ion microscopy to permit detailed indenter characterization. This perspec...
متن کاملAn ignition key for atomic-scale engines.
A current-carrying resonant nanoscale device, simulated by non-adiabatic molecular dynamics, exhibits sharp activation of non-conservative current-induced forces with bias. The result, above the critical bias, is generalized rotational atomic motion with a large gain in kinetic energy. The activation exploits sharp features in the electronic structure, and constitutes, in effect, an ignition ke...
متن کاملControl of friction on the atomic scale
“The modern world depends upon the smooth and satisfactory operation of countless tribological systems.” B.N.J. Persson Measuring and controlling friction on the atomic scale is the main goal of this thesis. Nowadays, fundamental studies of friction on nanometer-scale are mandatory, since frictional forces become more and more relevant as the scale of nanoelectromechanical devices is reduced. D...
متن کاملAn Accuracy Algorithm for an Atomic Time Scale
The accuracy of the rate or frequency of an atomic time scale is the degree to which its unit agrees with the SI second. Primary frequency standards are constructed in such a manner that t,hey provide the most accurate possible physical realization of the SI second. These standards are then used to calibrate or construct an atomic time scale which may also be used as a stable reference standard...
