Physical Review Letters 111, no. 16: 166401.0031-90071079-7114http://nrs.harvard.edu/urn-3:HUL.InstRepos:12220372We show that the Néel states of two-dimensional antiferromagnets have low energy vector boson excitations in the vicinity of deconfined quantum critical points. We compute the universal damping of these excitations arising from spin-wave emission. Detection of such a vector boson will demonstrate the existence of emergent topological gauge excitations in a quantum spin system.en-USJournal Article2014-05-2810.1103/physrevlett.111.166401
