dc.description© 2011 American Physical Society. We thank N.G. Fytas for his comments on our manuscript. Our simulations were performed on the Red Española de Supercomputación and at BIFI (Terminus and Piregrid). We acknowledge partial financial support from MICINN, Spain (Contract No. FIS2009-12648-C03) and from UCM-Banco de Santander (GR32/10-A/910383). D.Y. was supported by the FPU program (Spain).
dc.description.abstractWe study the critical behavior of the diluted antiferromagnet in a field with the tethered Monte Carlo formalism. We compute the critical exponents (including the elusive hyperscaling violations exponent θ). Our results provide a comprehensive description of the phase transition and clarify the inconsistencies between previous experimental and theoretical work. To do so, our method addresses the usual problems of numerical work (large tunneling barriers and self-averaging violations).
