Dipole plasmon resonances are described quantum mechanically using configuration interaction (CI). A fictitious system of three interacting configurations is considered, which yields three excited states. Excited states energies and oscillator strengths are derived from the eigenvalues and eigenvectors of the CI matrix, where the diagonal elements α(i) (i = 1, 2, 3) correspond to the interactin...

We use Faddeev’s decomposition to solve the shell-model problem for three nucleons. The dependence on harmonic-oscillator excitations allowed in the model space, up to 32h̄Ω in the present calculations, and on the harmonicoscillator frequency is studied. Effective interactions derived from Nijmegen II and Reid93 potentials are used in the calculations. The binding energies obtained are close to ...

We present an innovative adaptive, model following control scheme and apply it to control a chaotic system with unknown parameters. We illustrate the proposed approach with control of Duffing oscillator problem. The same idea is used to solve three important problems: suppression of chaos, anticontrol of chaos and chaos synchronization. We propose to use ‘approximators’ linearly parameterized b...

In this report the problem of forming chaotic signals with prescribed spectrum is discussed. An approach to construction of single-transistor chaotic oscillators with preassigned spectrum on the basis of “active component (transistor) – passive quadripole closed in feedback loop” structure is proposed. On example of capacitive three-point oscillator it is shown that in the oscillator with such ...

single-valence electron atoms are an important class of atoms. their oscillator strengths are their important properties. knowing the oscillator strengths one can easity calculate the transition probabilities of the spectral lines and hence the lifetimes of energy levels of most atoms. the oscillator strengths of the spectral lines of most atoms are not knoen with sufficient accuracy due to the...

After reviewing the covariant description of Hamiltonian dynamics, some applications are done to the non-relativistic isotropic three-dimensional harmonic oscillator, Rovelli's model, and SO(3, 1) BF theories.
