摘要

The universality class of a phase transition is often determined by factors like dimensionality and inherent symmetry. We study the magnetic dipole system in which the ground-state symmetry and the underlying lattice structure are coupled to each other in an intricate way. A two-dimensional (2D) square-lattice system of magnetic dipoles undergoes an order-disorder phase transition belonging to the 2D Ising universality class. According to Prakash and Henley [Phys. Rev. B 42, 6572 (1990)], this can be related to the fourfold-symmetric ground states, which suggests a similarity to the four-state clock model. Provided that this type of symmetry connection holds true, the magnetic dipoles on a honeycomb lattice, which possess sixfold-symmetric ground states, should exhibit a Kosterlitz-Thouless transition in accordance with the six-state clock model. This is verified through numerical simulations in the present investigation. However, it is pointed out that this symmetry argument does not always apply, which suggests that factors other than symmetry can be decisive for the universality class of the magnetic dipole system.

B 42，6572（1990）]，这可能与四重对称基态有关，这表明与四态时钟模型相似。只要这种对称连接成立，具有六重对称基态的蜂窝状晶格上的磁偶极子就应根据六态时钟模型表现出Kosterlitz-Thouless跃迁。这在本研究中通过数值模拟得到了验证。但是，需要指出的是，这种对称性论点并不总是适用，这表明除了对称性之外的其他因素对于磁偶极子系统的通用性也可以起决定性作用。
