The International Workshop on Topological Structures in Ferroic Materials (TOPO) was established as an ad hoc meeting and was first held in 2015 at the University of New South Wales in Sydney as a reaction of the ferroelectric community to the rising attention towards topological defects like magnetic vortices, Bloch walls, skyrmions, merons, etc. and to the rising interest in various topological concepts such as winding numbers or homotopy groups. There is a strong cross-disciplinary dimension to the workshop with significant attendance by experts outside of the ferroelectric community. The first meeting offered a stimulating environment and resulted in subsequent fruitful meetings in Dresden (2016), Leeds (2017), Natal (2018), and Prague (2019). The sixth TOPO meeting in Berkeley in 2020 will continue this mission by bringing together the forefront of scientific experts as well as young scientists interested in topological aspects of magnetic, superconducting, ferroelectric, liquid crystal matter, etc. to provide a mutually beneficial meeting that highlights the beauty and connections of the unifying scientific concepts.
