“#Melting a crystal topologically” Upper panel: spin configuration of a skyrmion. Lower panel: Voronoi tessellation of representative skyrmion lattice configurations in the solid, the hexatic and the liquid phases respectively. Credit: Huang Ping (Xi’an Jiaotong University) The introduction of topology, a branch of mathematics focusing on the properties of ‘knots,’ into physics has inspired revolutionary…
