From 27th October to 4th November 2019 Ivke visited NIFS (National Institute for Fusion Science) in Toki, Japan, as a member of University of Belgrade delegation headed by rector Ivanka Popović, who signed an Agreement of collaboration between NIFS and University of Belgrade.
Ivke, Bratislav Obradović (Faculty of Physics), Milan Rajković (Institute of Nuclear Sciences Vinca) and Milica Ilić (Faculty of Mechanical Engineering) had a fruitful discussions with Japanese colleagues and made plans for future common projects.
- ELI attosecond in Szeged (HU);
- High voltage laboratory in Brno (CZ), where they work with 120 kA currents and 2 MV voltages;
- Helmholtz‐Zentrum Dresden‐Rossendorf in Dresden (D) seeing Ion Beam Facility and Radiation Source ELBE;
- ELI beams and Institute of Plasma Physics in Prague (CZ), latter one showed him COMPASS tokamak and PALS ion laser.
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 .

Ivke visited the Extreme Light Infrastructure (ELI) in Bucharest with colleagues from Physical Faculty (Belgrade). The visit was realized as part of the project “Laser induced plasmas: Spectroscopic diagnosis and applications in photonic and bio nanotechnologies” through the Romanian Academy of Sciences. The visit was realized from 3rd to 7th October 2016.
