对“用同步更新模式的Glauber动力学研究一维Ising铁磁体零温下的相变”一文的评论
Comment on "Phase transition in a one-dimensional Ising ferromagnet at zero temperature using Glauber dynamics with a synchronous updating mode"
摘要:
Sznajd-Weron在[Phys. Rev. E { \bf 82},031120(2010)]中提出,服从零温度同步Glauber动力学的一维伊辛模型表现出不连续的相变。相反,我们在这里表明,相变是一个连续的性质,并确定关键指数:$β\approx 0$,$ν\approx 1$,和$z \approx 2$,通过系统的有限尺寸标度分析。
英文摘要:
Sznajd-Weron in [Phys. Rev. E {\bf 82}, 031120 (2010)] suggested that the one-dimensional Ising model subject to the zero temperature synchronous Glauber dynamics exhibits a discontinuous phase transition. We show here instead that the phase transition is of a continuous nature and identify critical exponents: $β\approx 0$, $ν\approx 1$, and $z \approx 2$, via a systematic finite-size scaling analysis.
