Flux pinning mechanism of graphene oxide (GO) doped MgB2 has been systematically studied. In the framework of the collective pinning theory, a B-T phase diagram has been constructed. By adjusting the GO doping level, the pinning mechanism in MgB2 transformed from transition temperature fluctuation induced pinning, δTc pinning, to mean free path fluctuation induced pinning, δl pinning, is observ...

We study the dynamic critical behavior of two algorithms: the Swendsen– Wang algorithm for the two-dimensional Potts model with q = 2, 3, 4 and a Swendsen–Wang–type algorithm for the two-dimensional symmetric Ashkin– Teller model on the self-dual curve. We find that the Li–Sokal bound on the autocorrelation time τint,E ≥ const × CH is almost, but not quite sharp. The ratio τint,E/CH appears to ...
