The journal Scientific Reports published on May 20, 2016 the article entitled “Points, skyrmions and torons in chiral nematic droplets”, by Gregor Posnjak, Simon Čopar and Igor Muševič, members of the Solid State Department (F5) of JSI and Faculty of Mathematics and Physics, University of Ljubljana. They discovered a new method of reconstructing 3D orientational field of a liquid crystal, labelled with fluorescent molecules and imaged with a confocal optical microscope. Using this method they were able for the first time to determine unambigously the topological properties of a chiral liquid crystal, captured in a micro-droplet, as tiny as a hair. They could see singular point-like topological defects, separated by 3D topological objects, which are known in physics as skyrmions and torons.
Awards 2016
Dr. Matjaž Humar: 1st Place Poster Prize at prestigious Nobel Laureate Meeting 2016, Lindau, Germany. Matjaž presented a poster about lasers embedded into single live cells for the first time. He has also demonstrated that fat cells already present in the human body already contain tiny lasers, which only need to be activated.
Dr. Matjaž Humar: Bronze Award from community Šempeter-Vrtojba for 2016, Šempeter-Vrtojba. The prize for the high successes in the world scale in recent years and as a stimulation for further scientific work.
dr. Janez Pirc: Hononrary distinction of “Jožef Stefan” Institute, Ljubljana, Slovenia, Honorary distinction for his successful contribution tor developing new high-tech products based on scientific and technological achievements of the “Jožef Stefan” Institute.
