Theory Of Light Hydrogenic Bound States

Employing a two dimensional electron gas in a semiconductor as a normal conductor opens up the possibility to observe effects not found in purely metallic junctions.By combining heterostructures with su perconductors, many of the effects found in purely semiconductor systems can in a sense, be transferred to the superconducting state. Special care is taken on explaining the underlying theoretical concepts related to the transport mech anisms.

Surface Scattering Experiments with Conduction Electrons shows how this process can be used to investigate surface processes of thin metal films. The in situ observation of epitaxial growth is additionally shown to be possible. Since a thin film is in one direction of a size comparable to the mean free path of the conduction electrons, such a film is both substrate and sensor and must be characterized by other surface-analytical methodsas demonstrated here..

Dispersion relations and methods of analysis in optical spectroscopy are derived with the aid of complex analysis.. The book includes new methods such as the maximum entropy model for wavelength-dependent spectra analysis.Dispersion, Complex Analysis and Optical Spectroscopy In addition, it presents the dispersion theory of the nonlinear optical processes which are essential in modern optical spectroscopy.

We discuss the influence of the substrate material and the annealing treatment of the films, presenting our experimental data as well as theoretical models to calculate the scattering cross section of the conduction electrons in the frame-work of the scattering hypothesis.. Main emphasis is laid on the comparison of gold and silver films which exhibit nearly the same lattice structure but differ in their chemical activity. Z can be calculated on the basis of the density functional formalism or the self-consistent field approximation using Mulliken’s population analysis.

The re- tivistic spin one half Dirac equation quantitatively described the main - perimental features of the hydrogen spectrum. Despite its long and rich history the theory of atomic bound states is still very much alive today.

The re- tivistic spin one half Dirac equation quantitatively described the main - perimental features of the hydrogen spectrum. The Bohr quantization rules of the old quantum theory were created in order to explain the existence of the stable discrete energy levels. Each step in the development of quantum physics led to a better understanding of the bound state physics.

The very discovery and further progress of quantum mechanics is intimately connected to the explanation of the main features of hydrogen energy levels.New importance to the bound state physics was given by the development of quantum chromodynamics, the modern theory of strong interactions.
