SUMMARY:Lukyanchuk: Topology in Ferroelectric vs. Topology in Magnetism 
CLASS:PUBLIC
DESCRIPTION:Speaker: Prof. Dr. Igor Lukyanchuk\nInstitute of Speaker: Unive
 rsity of Picardie\, Amiens/France\nTopics:\n\n Location:\n  Name: IFW (D2E

   Phone: \n  Fax: \nDescription: . We present the advancements in nanostru
 ctured ferroelectrics\, focusing on the discovery of novel topological pol
 arization structures. We challenge the initial interpretation of these str
 uctures - vortices\, skyrmions\, merons\, and others - which were analogiz
 ed to magnetic systems based on real-space vector field topology. However\
 , this approach overlooks the pivotal role of long-range electrostatic for
 ces in ferroelectricity. By presenting a new topological framework\, topol
 ogical hydrodynamics of ferroelectricity\, which is centered on the electr
 ostatic essence of ferroelectricity. We revise recent trends and observed 
 structures in the field. Our analysis categorizes these complex structures
  into fundamental formations: vortices and Hopfions. The emergence of Hopf
 ions is particularly notable for introducing chirality into confined ferro
 electric systems\, offering a richer understanding of these materials. .
