Berezinskii-Kosterlitz-Thouless phase transitions of the antiferromagnetic Ising model with ferromagnetic next-nearest-neighbor interactions on the kagome lattice
Yutaka Okabe, Hiromi Otsuka
We investigate the six-state clock universality of the Ising model on the kagome lattice, considering antiferromagnetic nearest-neighbor (NN) and ferromagnetic next-nearest-neighbo…
Comment on CFT in AdS and boundary RG flows: O(1/N) Result
Kaoru Ohno, Yutaka Okabe
In a recent paper [JHEP 11 (2020) 118], S. Giombi and H. Khanchandani studied the 1/N expansion of the O(N) model in semi-infinite space within the framework of conformal field the…
BKT transitions of the XY and six-state clock models on the various two-dimensional lattices
Yutaka Okabe, Hiromi Otsuka
In a two-dimensional (2D) spin system, the XY model, characterized by planar rotational symmetry, exhibits a unique phenomenon known as the Berezinskii-Kosterlitz-Thouless (BKT) tr…
Ising model on the aperiodic Smith hat
Yutaka Okabe, Komajiro Niizeki, Yoshiaki Araki
Smith et al discovered an aperiodic monotile of 13-sided shape in 2023. It is called the `Smith hat' and consists of 8 kites. We deal with the statistical physics of the lattice of…
Probability-Changing Cluster Algorithm for Potts Models
Yusuke Tomita, Yutaka Okabe
We propose a new effective cluster algorithm of tuning the critical point automatically, which is an extended version of Swendsen-Wang algorithm. We change the probability of conne…
