Symposium EQ08-Higher-Order Topological Structures in Real Space—From Charge to Spin

Real space structures with non-trivial topology, such as skyrmions, merons, dislocations and domain walls, are rich sources for emergent functional phenomena, enabling local control of magnetic, electronic and ionic transport properties, light-matter interactions, propagation of (electro)magnons and phonons, and more. The concept of topology has led to a strong cross-disciplinary dimension connecting the ferroelectrics and the magnetism communities. It is now clear that higher-order topological charge and spin textures open up a plethora of possible future dynamic nanoelectronics, spintronics and quantum devices. The beauty and connections of the unifying scientific concepts in materials with electric and / or magnetic order are mutually beneficial and have become a strong motivation for interdisciplinary activities, propelled by the recent developments in theory, synthesis and characterization.

This symposium aims to bring together scientific experts and young scientists with an interest in topologically non-trivial charge and spin textures that arise in real space, fostering interactions and advancing knowledge of higher-order topological structures in ferroelectrics, multiferroics and magnetic materials.

Topics will include:

  • Skyrmions and chiral textures, higher-order topological structures
  • Domains and domain walls, dislocations and disclinations
  • Time-resolved and ultrafast measurements
  • In-situ/operando characterization of dynamic processes via electron and local probe microscopy
  • Three dimensional characterisation and reconstruction of higher order topologies
  • Atomic-scale charge, spin and phonon characterization
  • Controlled formation and movement of topological structures
  • Materials (bulk crystals, thin films, superlattices, 2D systems)
  • Emergent functional properties
  • Interactions with extrinsic and intrinsic defects
  • Vortex, anti-vortex, and vertex structures
  • Nanoelectronics using topological defects
  • Theoretical simulation and modeling of mechanically, electrically and magnetically driven processes
