After succesful presentaton at Automatica fair in Munich last year, researchers from Dept. of Automatics, Biocybernetics, and Robotics Timotej Gašpar, Martin Bem and Robert Bevec are this year presenting the results of H2020 innovation action ReconCell (A Reconfigurable robot workCellfor fast set-up of automated assembly processes in SMEs) at the largest industrial fair in the world, the Hannover Messe. Our presentation focuses on a new solution for automated assembly of automotive lights, which we developed in collaboration with a Slovenian SME Elvez. Our solution is distinguished by the application of new reconfiguration technologies, which enable the automated assembly of different lights in the same workcell without manual intervention. On the first day of the fair, our booth was visited also by European commissioner Günther Oettinger.
Researchers of the Laboratory for Cold Atoms at the Condensed Matter Physics Department F5 have confirmed Bose-Einstein Condensation (BEC) of Cesium atoms on March 31, 2017. They used the laser light to cool Cesium atoms to temperatures near absolute zero (below 20 nK) and compressed them into BEC using light and magnetic fields. The picture shows cooling and compression of cold atoms into BEC, forming a coherent cloud of 50 microns diameter containing 15.000 atoms. In this fascinating quantum matter, quantum physics is observable at the macroscopic level, making it an ideal system to simulate quantum phenomena, study quantum computing, or using quantum physics for metrology. With this achievement the Department joined a prominent laboratories performing experiments in quantum technologies.
New super-resolution STED microscope has been installed at the Condensed matter department (F5) which enables 3D imaging of up-to 100 m thick fluorescently labeled transparent matter, such as biological or soft samples. STED microscope has an impressive 30 nm lateral resolution and uses two-photon excitation to image in greater depth, achieving still superior resolution of 200 nm. Special gated detection system with time resolution of 100 ps enables mapping of the fluorescence lifetime to characterize the interactions between the fluorescent probes and environment.

Journal Nature Communications published an article entitled Hidden topological constellations and polyvalent charges in chiral nematic droplets, which was written by Gregor Posnjak, Simon Čopar and Igor Muševič, researchers of the Condensed Matter Physics (F5) department of JSI and Faculty of Mathematics and Physics, University of Ljubljana. The authors used an advanced method of 3D fluorescent confocal microscopy to reconstruct the order of molecules in micrometre-sized droplets of chiral nematic liquid crystals and discover various topological states which include strings of topological defects and point defects with multiples of unit topological charge. The ordering of molecules around these topological defects is similar to polyvalent atoms and enables the formation of complex topological structures, reminiscent of molecules.
