Abstract, Event Details:
The term »topological soft matter« is used for systems with stable defects in the orientational order-parameter field. In nematogenic liquid crystals interplay of confining geometry, surface anchoring, elasticity, chirality often lead to frustration and consequently to stable or metastable disclinations and solitonic deformations. Recently a lot of attention has been devoted to blue phases and confined & colloidal nematics. Here I present two of our recent achievements based on the synergy of numerical modeling and experiments: i) detection of skyrmion lattices in confined blue phases and ii) sensing the surface morphology of biofibers with nematic drops.
Studies were performed within local and international collaborations including S. Čopar, J. Fukuda, E.M. Godinho I. Muševič, A. Nych, U. Ognista, M. Ravnik, D. Seč, and M. Škarabot.
