Article in Science Advances
The article Mosaics of topological defects in micropatterned liquid crystal textures written by Dae Seok Kim and Dong Ki Yoon from the KAIST Institute in South Korea, Simon Čopar from the Faculty of Mathematics and Physics, University of Ljubljana, and Uroš Tkalec, associate of the Condensed Matter Physics Department at the Jožef Stefan Institute, was published in the Science Advances journal. The article presents an experimental method of controlled creation of micropatterned topological defects in thin layers of nematic and smectic phases in liquid crystals using micropatterned surfaces. The created patterns are very robust, colourful and responsive to the changes in the thickness of the layer and the temperature. The patterns can cover several square centimetres of the surface, follow the symmetrical rules on topological charge conservation and look like ceramic or glass mosaics or stained glass patterns.

Dr. Posnjak’s doctoral thesis published by Springer
Monograph Topological formations in chiral nematic droplets written by Gregor Posnjak from the F5 Department has been published by Springer. The book was published in the Springer Theses series, which focuses on dissemination of outstanding and relevant doctoral theses. Dr. Posnjak’s theses, which he defended in 2017 at the Faculty of Mathematics and Physics of the Univeristy of Ljubljana under the mentorship of prof. dr. Igor Muševič, discusses complex structures of chiral nematic liquid crystals. In his theses, Dr. Posnjak reported the first observation of topological point defects with higher topological charges q = −2 and q = −3 and developed a new augmented fluorescent confocal polarising microscopy method for reconstruction of director fields in experimental conditions.
