Abstract
Hwang in [Phys. Rev. E 80, 042103 (2009)] suggested that the two transitions of the six-state clock model on the square lattice are not of the Kosterlitz-Thouless type. Here we show from simulations that at the upper transition, the helicity modulus does make a discontinuous jump to zero. This gives strong evidence for a Kosterlitz-Thouless transition.
摘要
黄（在《物理评论E》第80卷，042103（2009年）中）提出，正方晶格上六态时钟模型的两个转变并非科斯特利茨 - 索利斯类型。在此我们通过模拟表明，在上转变处，螺旋度模量确实会不连续地跃变为零。这为科斯特利茨 - 索利斯转变提供了有力证据。
