Theses metadata

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.

Abstract:	In this thesis, we analyzed some of the coherent effects – electromagnetically induced transparency and spontaneously generated coherence – that can appear in the interaction of the confined hydrogen atom with laser fields. It is studied the possibility to manipulate the group velocity of light in the medium under the condition of electromagnetically induced transparency. The model is then used to analyze the hydrogenic impurity in the spherical and the multilayered spherical quantum dot. Coherent effects are investigated in different configurations – three-level and four-level cascade configuration and four-level Y configuration. Absorption and dispersion properties of the systems for probe laser field are obtained by solving master (optical Bloch) equations in stationary regime and by using the connection between corresponding elements of the density matrix with the susceptibility of the system for a probe laser field. Behavior of the mentioned variables are then discussed in detail as a function of the radius of confinement, intensity of the control laser fields, detunings of the control and probe laser fields and intensity of the external magnetic field, if it is present. Coherent effects were also considered in the dressed state basis for each of the configurations. Finally, we propose a few problems for further research on these topics.
