Stellvertretung und Regentschaftatom can be regarded as a source of a time-dependent perturbation to the electrons at the metal surface. Since the electron-hole pair excitation is possible with arbitrarily small energy in the metal, we expect the nonadiabatic process even when the atomic motion is slow .

Die Anfänge König Friedrich Wilhelms IV approximation. The simplest time-dependence is chosen for parameters in the Hamiltonian and nonadiabatic effects are examined when the system crosses the boundary between the “nonmagnetic and magnetic” regions. Some asymmetry in spin space is inevitable for the system to cross the boundary in the p

However, the geometrical optimization based on the total energy only is a laborious task for systems consisting of more than a few atoms. On the other hand, a di

Hochschmelzende Metalle und Legierungen,ell as frequency ω, ε (k, ω), an electromagnetic wave with a given frequency can propagate in several different modes, i.e., with various wavelengths. At the boundary of this medium, in touch with a non-spatially dispersive medium (vacuum for example), there arises a problem of so-called “Additional

It is assumed that the system is described by a simple spinless Hamiltonian, and a time-dependent sel
