This project deals with various new realizations in the field, based on artificial atoms, investigated with a focus on their role in developing novel sources of light as well as on manipulation of the quantum dissipation in these systems.

A rigorous treatment of light interaction with a few-particle quantum-dot sample and a corresponding manipulation, and adequate description of entanglement creation in these systems was done.

The main objectives of the project were:

• development of new techniques of describing the collective interactions among artificial atoms (i.e., quantum dots or wells).
• revealing of methods of manipulation of the non-linear quantum dynamics of strongly coupled few-level entangled systems;
• investigation of the feasibility of inhibition of the quantum dissipations due to spontaneous emission of radiation in artificial-atom systems; special attention will be paid to nano-photonics in ultra-strong coupled fields;
• elucidation of the methods of creation of strongly correlated photons in systems of quantum dots coupled with an external coherent field and a microcavity;
• establish the application perspectives of project results to new ways of obtaining controlled THz light radiation.

This project was funded by Supreme Council for Science and Technological Development (Academy of Sciences of Moldova) and Federal Ministry of Education and Research (BMBF, FRG). Project team was divided into two local teams headed by Mihai Macovei, Dr.Sci. (Institute of Applied Physics, Chisinau, Rep. of Moldova) and Prof. Christoph Keitel (Max Planck Institute for Nuclear Physics, Heidelberg, Germany).
