Using extensive stochastic series expansion quantum Monte Carlo simulations, we perform very long runs for an LxLxL lattice up to L = 48. By employing a standard finite-size scaling method, the numerical values of the Neel temperature are determined with high precision as a function of the coupling ratio r = J(2)/J(1). Based on the estimated critical exponents, we find that the critical behavior of the considered model belongs to the pure classical three-dimensional O(3) Heisenberg universality class.eninfo:eu-repo/semantics/openAccessPhase-TransitionMonte-CarloDisorderFluctuationsTemperatureImpuritiesOrderUniversality in the three-dimensional random bond quantum Heisenberg antiferromagnetArticle10.1103/PhysRevB.102.0644112-s2.0-850901554226Q1102WOS:000559733500005Q2
