Yesterday, the Laboratory hosted Dr. Predrag Ranitović, who held an open lecture at Institute of Physics Belgrade. The lecture title was “Attosecond Coherent Control of Atomic and Molecular XUV and X-Ray Absorption Processes by Intense Laser Radiation”.
Recent breakthroughs in the ultrafast lasers development have allowed for the opening of new horizons in the ultrafast experimental and theoretical AMO physics. Following these advances, table-top light sources have provided novel ways to achieve a real-time manipulation of the correlated electron/nuclear wavepacket dynamics by means of attosecond XUV and femtosecond IR radiation [1-6]. However, more than fifteen years upon the birth of attosecond physics, and after the Nobel Prize Award for femtochemistry, the concept of attosecond chemistry has not yet been fully realized. In this talk, I will introduce the basic principles of the strong laser-field ionization and generation of attosecond XUV/X-Ray radiation, and show how the attosecond VUV and XUV light sources can be used to coherently manipulate molecular dynamics by means of electron wave packet interferometry [7-9]. The use of attosecond VUV pulse-trains to coherently excite and control the outcome of a simple chemical reaction in a deuterium molecule, in a nonBorn-Oppenheimer regime, presents intriguing new possibilities for bridging the gap between the attosecond physics and attochemistry . Furthermore, I will discuss very recent results that extend the use of the attosecond table-top techniques to the soft X-Ray regime in the water window .

All members of the laboratory participated at the 29th Summer School and International Symposium on the Physics of Ionized Gases (SPIG 2018) held in Belgrade (Serbia). Again, Prof. Кonjević held the introductory talk. Ivke was member of the Scientific Committee for the third consecutive time. Marijana, Milica and Marko each presented the poster titled “Underwater Ablation with Two Different Laser Wavelength”, “Nanoparticles on a Sample Surface as Laser Induced Breakdown Spectroscopy Enhancers” and “Current Distribution in an Experiment of Z-Pinch with Pre-Embedded Axial Magnetic Field”, respectively. While Biljana and Miloš presented the progress reports on “Beryllium spectral line studies in the presence of beryllium dust” and “Studies or Runway Electrons in COMPASS Tokamak”, respectively.
We are also proud for having invited two lecturers. First, Vincenzo Amendola, an associate professor of physical chemistry in the Department of Chemical Sciences of Padova University (Italy) gave a plenary talk on the “Laser assisted synthesis of magneto-plasmonic and UV-vis-NIR plasmonic nanoparticles”. Next, Andrei Pipa, research associate at the Leibniz Institute for Plasma Science and Technology (Greifswald, Germany) held the talk on the “Equivalent circuit approach for electrical diagnostics of dielectric barrier discharges”. We would like to use this opportunity to thank them for coming.

Even though he was not present, Miloš contributed to the 45th EPS Conference in Plasma Physics, held in Prague (Czech Republic). The main contribution was part of the plenary talk “Runaway electron experiments at COMPASS in support of the EUROfusion ITER physics research” given my his PhD mentor, Jan Mlynar. The talk will hopefully result in the peer-review article (now we know it did: see the link). Additionally, Miloš also co-authored the poster contribution “Analysis of MGI disruptions and runaway electron beams at COMPASS using tomography and fast camera data” presented by Ondrej Ficker.

Ministry of Education, Science and Technological Development has approved promotion application of Marijana to Assistant Research Professor on 30th May.
Branimir Blagojević, our former member, is again collaborating with us. Namely with Ivke’s and Prof. Konjević’. Together they published the article on “Semiclassical calculations of stark broadening parameters of He I lines, revisited” in Journal of Quantitative Spectroscopy and Radiative Transfer.
We are happy to announce that Biljana’s article on “Novel plasma source for safe beryllium spectral line studies in the presence of beryllium dust” has been published in Review of Scientific Instruments. We are even more proud that the article was chosen for the AIP Editor Pick’s collection. Note that the significant contribution of co-authors should not overseen.
Ministry of Education, Science and Technological Development has approved job application of Miloš as part of the returnee-employment program. He is now full member of the Laboratory and project ON 171014.
Marijana’s collaboration with Poland has payed off. The article on “Study of Stark broadening of Li I 460 and 497 nm spectral lines with independent plasma diagnostics by Thomson scattering” has been published in Plasma Sources Science and Technology.
Scientific Board of the Institute of Physics Belgrade approved promotion of Miloš to research assistant.
