SILVA, Roberto da  y  DAHMEN, S. R.. Local persistence and blocking in the two-dimensional blume-capel model. Braz. J. Phys. [online]. 2004, vol.34, n.4a, pp. 1469-1472. ISSN 0103-9733.  http://dx.doi.org/10.1590/S0103-97332004000700027.

In this paper we study the local persistence of the two-dimensional Blume-Capel Model by extending the concept of Glauber dynamics. We verify that for any value of the ratio a = D/J between anisotropy D and exchange J the persistence shows a power law behavior. In particular for a < 0 we find a persistence exponent q_l = 0:2096(13), i.e. in the Ising universality class. For a > 0 (a ¹ 1) we observe the occurrence of blocking.
