原子系統的同調光控制(1/3)

In this joint project we will combine theoretical and experimental studies of coherent control and quantum optics phenomena in atomic media, including for Rydberg atoms, motivated by potential application to quantum computation and simulation using these systems. Theoretically designed novel methods for sub- wavelength two-dimensional (2D) and three-dimensional (3D) atom localization using optical vortices, as well as exchange of vortex light beams in media of interacting Rydberg atoms will be developed within the Riga-Vilnius-Taiwan collaboration. Feasible experimental setups for the realization of the such schemes, along with possible practical applications, will be proposed. In addition, we will investigate theoretically the non-Hermitian Hamiltonian and synthetic gauge fields for dark-state polariton in the Electromagnetically Induced Transparency (EIT). A systematic experimental and theoretical work on searching for Bose-Einstein condensation of Rydberg polaritons will also include the effects of different parameters on the Rydberg-EIT system, the Rydberg-polariton density, and the realization of Rydberg-polariton stationary light. Finally, on a more applied level, the project will deal with the development of a scientific method for a wide-range, high-spatial-resolution magnetometer in two consequent steps: for magnetic field dynamic cancellation and for high dynamic- range sensitive optical magnetometer based on absorption spectroscopy of alkali metal vapor.
