The Nankai team discovered a three-dimensional ferroelectric braided network with global topological protection
Recently, Professor Zhang Guoquan's team from the School of Physical Sciences at Nankai University, together with Professor Eugenio DelRe from the University of Rome in Italy, Professor Beatriz Noheda from the University of Groningen in the Netherlands, and Professor Aharon J. Agranat's team from the Hebrew University of Israel, discovered a three-dimensional ferroelectric woven network formed by spontaneous symmetry breaking in potassium lithium tantalum niobate (KTN: Li) ferroelectric crystals and achieved local optical control.
