Properties of the q-state clock model for q=4, 5, and 6. Tobochnik, J. Physical Review B, 26(11):6201–6207, December, 1982.
Properties of the q-state clock model for q=4, 5, and 6 [link]Paper  doi  abstract   bibtex   
The two-dimensional clock models for q=4, 5, and 6 were simulated on lattices of size 256 and 1024. Various properties were computed including the specific heat, susceptibility, vorticity, and correlation times. However, only a Monte Carlo renormalization-group analysis was capable of locating quantitatively the phase transitions for q=5 and 6. The results agree with the qualitative picture obtained for the Villain version of the clock model. The relevance of this work to the two-dimensional melting problem is discussed. MS code no. BT2080 1977
