DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMFNoT/23/">
 Exploring resemblance between liquid crystals topological defects and part
 icle physics</a>\nby Jarek Duda (JU) as part of QM Foundations & Nature of
  Time seminar\n\n\nAbstract\nThere are experimentally observed long-range 
 e.g. Coulomb-like interactions for topological defects in liquid crystals\
 , suggesting investigation how far can we take this resemblance with parti
 cle physics. I will discuss postulating skyrmion-like Lagrangian to get el
 ectromagnetism for their effective dynamics\, interpreting filed curvature
  as electric field - making Gauss law count (quantized) topological charge
 . For biaxial nematic - with 3 distinguished axes\, hedgehogs of one of 3 
 axes are different mass realizations of the same topological charge - rese
 mbling 3 leptons. Further baryon-like topological structures require charg
 e\, which has to be compensated for neutron - suggesting why it is heavier
  than proton. For analog of quantum phase there is derived Klein-Gordon-li
 ke equation\n
