Properties of few level atomic systems possessing a permanent dipole moment. — •Alexandra Mirzac — Insitute of Applied Physics, Academiei str.5, MD-2028, Chisinau, Moldova

The quantum optical properties of two- and three-level atomic systems interacting with electromagnetic field is an area of research directed to solve applied problems emerging in laser science, fluorescent spectroscopy, nano-imaging and quantum information theory.

Dipolar two-level atomic systems are widely researched to detect novel multiphoton features and terahertz emission properties. Three level atomic systems with permanent dipole moment include both the properties of a two- and three- level system simultaneously. One can switch between these properties as function of tunable Rabi frequency. Also, three-level system exhibit many coherent interference effects, which can serve as application for testing quantum protocols and information storage. For this reason, few level atomic dipolar systems are perspective setups for generation of tunable electromagnetic waves such as terahertz domain. Consequently, detection of effective terahertz radiation is an emerging task both for applied and theoretical quantum optics. Additionally, non-resonant multiphoton conversion from optical to microwave region is a feasible quantum technology, where few level dipolar systems can be used for solution development.

Thus, the permanent non-zero dipole moment improves the quantum optical properties of few level atomic system in comparison to the similar ones yet in the absence of the permanent dipole moment.
