Topološka mehka snov

 

Topološka mehka snov je specifična snov, pri kateri stabilni ali
metastabilni defekti v orientacijski urejenosti odločilno vplivajo na njeno
strukturo. 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.

Predavanje bo v angleščini.

Lepo vabljeni!

Topological soft matter

 

Topological soft matter is a specific matter where stable or metastable
defects in orientational molecular ordering crucially determine its
structure.  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.
