Critical behavior of the dilute antiferromagnet in a magnetic field

Fernandez, L.A. ; Martin-Mayor, V. ; Yllanes, D.

Resumen: We 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 ). 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).
