Impurity spin textures across conventional and deconfined quantum critical points of two-dimensional antiferromagnets

Abstract

We describe the spin distribution in the vicinity of a non-magnetic impurity in a two-dimensional antiferromagnet undergoing a transition from a magnetically ordered Néel state to a paramagnet with a spin gap. The quantum critical ground state in a finite system has total spin S = 1/2 (if the system without the impurity had an even number of S = 1/2 spins… (More)
