Tarancón, G. Parisi, and P. Young for discussions. Simulations were performed at BIFI (Terminus, 6.6 × 10^(5) hours of CPU time) and Red Española de Supercomputación (Caesaraugusta, 2.79 × 10^(5) hours), whose staff we thank for the assistance provided. We were partly supported by MICINN (Spain) through research contract No. FIS2009-12648-C03 and (S.P.G.) through the FECYT Foundation.We perform a finite-size scaling study of the three-dimensional Heisenberg spin glass in the presence of weak random anisotropic interactions, up to lattice sizes L = 32. Anisotropies have a major impact on the phase transition. The chiral-glass susceptibility does not diverge due to a large anomalous dimension. It follows that the anisotropic spin glass belongs to a Universality Class different from the isotropic model, which questions the applicability of the chirality scenario.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.84.024419https://journals.aps.orgopen access53Antiferromagnetic RP(2) model3 dimensionsMonte-CarloCritical-behaviorField-theoryBerry phaseManganitesSimulationChiralityFísica-Modelos matemáticos
