Stabilizacijo topoloških defektov, kot so zavozlana orientacijska polja, omogoča ravnotežje med nasprotujočimi učinki ograditve, zunanjih polj ali kiralnosti. Primeri so tekoče kristalne faze v kompleksnih geometrijah, koloidih in kompozitih. Karakterizira jih izrazito velika odzivnost na zunanje vplive, zmožnost samourejanja in enostavno prilagajanje fizikalnih lastnosti za njihovo potencialno uporabo v fotoniki, optiki in senzoriki. V okviru predavanja bomo predstavili topološko mehko snov in opisali naše novejše dosežke, ki lepo ilustrirajo tudi pomen sinergije eksperimentalnih, numeričnih in teorijskih pristopov.<i><o:p></o:p></i></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v angleščini.<span style='mso-fareast-language:SL'><o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><strong><span style='font-family:"Calibri","sans-serif";color:red'>Lepo vabljeni!</span></strong><strong><span style='font-weight:normal'><o:p></o:p></span></strong></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal align=center style='text-align:center'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'>*****<o:p></o:p></span></p><p class=MsoNormal align=center style='text-align:center'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:black'>We invite you to the 5th Institute colloquium in the academic year 2013/14.

The stabilization of complex topological defects including knotted ordering fields is realized by a balance of conflicting effects like confinement, external fields, and/or intrinsic chirality. Typical examples are liquid crystalline phases in complex geometries, colloids, and composites. They are characterized by high susceptibility to external stimuli, easy directed assembly, robust structures, and simple tuning of physical properties that make them potentially useful for applications in optics, photonics, plasmonics, sensorics, and related technologies. In the talk we will introduce topological soft matter and present some of our recent achievements resulting from the synergy of experimental, numerical and theoretical approaches</span>.<o:p></o:p></p><p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p></div></body></html>
