Mikayel Khanbekyan's visit to the 'Hot Vapor Workshop 2024'
From September 30 to October 2, 2024, the 'Hot Vapor Workshop 2024' took place at the University of Stuttgart, Germany. Among the participants was Dr. Mikayel Khanbekyan, head of the research group 'Quantum optics for sensing and communication' at the Institute of Physical Research of the National Academy of Sciences of Armenia (IPhR). During the workshop, he delivered an oral presentation titled 'Atomic Vapor Spectroscopy on the Nanoscale: Refraction Enhancement Towards Vapor-Guided Light Propagation.' This trip was conducted as part of the 22IRF-06 project, funded by the HESC of RA."
Ara Tonoyan visited Mainz, Germany to the group of Prof. Dr. Dmitry Budker
Dr. Ara Tonoyan visited Mainz, Germany for three months within the HESC project 23-2PTS-1C004. He worked, in particular on the following:
Atmospheric turbulence poses a significant challenge to the performance of large optical telescopes by distorting the wavefront of light from celestial objects. This distortion results in blurred images and limits the telescopes' resolution. Adaptive optics systems are employed to correct these wavefront deviations, typically using a bright star as a reference. However, the availability of bright natural stars for this purpose is limited in the visible sky. To overcome this, artificial stars, known as Laser Guide Stars (LGS), are created in the mesosphere by exploiting the resonant interaction between sodium atoms and laser light. Extensive laboratory experiments have been conducted to study the properties of light scattered from sodium vapor, providing detailed insights into its behavior and characteristics.
Anahit Gogyan's research trip to Mainz, Germany to the group of Prof. Dr. Dmitry Budker
Dr. Anahit Gogyan contributed to the ongoing research in Prof. D. Budker's group from February 1 to April 4. Her theoretical work focused on studying the scattering of thorium ions during collisions with calcium ions. In the experimental setup, thorium ions with a kinetic energy of 500 keV, generated through laser ablation, collided with four to five calcium ions confined within a Paul trap. She calculated key parameters such as the scattering cross-section, collision probability, and related properties. Additionally, she contributed to the development of a computer program designed to evaluate the coherence of light sources.
