Coherent many-body exciton in van der Waals antiferromagnet NiPS3

An exciton is the bosonic quasiparticle of electron–hole pairs bound by the Coulomb interaction 1 . Bose–Einstein condensation of this exciton state has long been the subject of speculation in various model systems 2 , 3 , and examples have been found more recently in optical lattices and two-dimens...
