Abstract (en)
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.
