Dipolar lineons in a hole-doped collinear antiferromagnet

POSTER

Abstract

Fractons are emergent quasiparticles, which have fractionalized (reduced) mobility. In this talk we demonstrate the emergence of fracton conservation laws in a hole-doped collinear antiferromagnet in two dimensions. Using a combination of  analytical and numerical approaches we show that these systems host fracton-like quasiparticles, which are completely immobile in isolation, and dipolar quasiparticles that can move freely only along one dimensional subspace of the system.  We discuss possible experimental realizations of these observations.
