Operation co-funded by EU cohesion policy (European Social Fund (ESF)) under the programme EU Structural Funds Investments - LT - ERDF/ESF/CF/YEI (2014LT16MAOP001), managing authority: Finansų ministerija. The source names no beneficiary for this operation. Location: Vilnius County (NUTS LT011); Lithuania. Budget: total eligible expenditure EUR 85,008.28; EU co-financing EUR 85,008.28 (co-financing rate 100%), as stated by the source. Runs 2020-09-14 to 2022-09-13.

Summary from Kohesio (English machine translation by the source): During the postdoctoral internship, it is planned to examine new ways of manifesting the interaction of eddy light fibres with atoms in space. It is intended to investigate the location of cold atoms below the wavelength of light in a space area using a coherent interaction between light vortex and atoms. This question is important because the diffraction threshold usually limits the resolution. In addition, it is planned to investigate the interaction of optical vortex with Rydberg atoms, which have recently been very interested in their ability to process quantum information. The project consists of three phases, each with a duration of around 8 months. In the first stage, the trainee will investigate the localisation of atoms using their coherent interaction with optical vortex. It is expected that the atoms can then be localised in the wavelength range at lower radiation intensity than in the case of previously used non-coherent light. This should help localise atoms in an earlyer space area. In the second phase, the interaction of Rydberg atoms with optical vortex will be investigated. The trainee will explore how Rydberg’s atoms can be localised in all three directions of space, using stationary waves and optical vortex simultaneously. A standing wave should ensure the longitudinal localisation of atoms in the direction of light slipping, and the field of optical vortex should ensure transverse localisation. In the third stage, the trainee will investigate the transfer of optical vortex to atoms using Rydberg states. The results of the project are expected to be used as direct recommendations for experimenters investigating cold atoms. The trainee’s work in the post-doctoral project will help to improve his scientific qualification by solving the relevant tasks of atomic physics and quantum optics, and will expand the trainee’s horizons in this and other areas of physics.
