DESCRIPTION:In physics a central question regards the nature of elementary
  constituents in our universe are\, and how they interact. The properties 
 of the particles that we have uncovered are closely related to\, and there
 fore limited in their richness by\, the nature of the vacuum in our univer
 se. Over the years it has also become apparent that new and exciting vacua
  can be realised when a large number of particles are brought together whi
 ch strongly interact: these vacua can come with new `emergent’ particles
 . This forces us to revisit our understanding of elementary particles\, an
 d at times to turn it on its head. The new vacua can be highly exotic in n
 ature\, with unusual correlations often described as `topological’. Thei
 r emergent particles correspondingly exhibit unprecedented properties\, su
 ch as the separation of spin and charge in electronic systems\; to particl
 es that behave neither like fermions nor bosons\; and finally to a long so
 ught-after freely mobile magnetic charge. After years of a global research
  effort\, we are gradually developing the tools to understand and control 
 these new emergent particles\, and we are ready to start exploring their e
 nticing potential.
