Potts Model with the Simplest Modulated Phase
Nasir Ganikhodjaev,Seyit Temir,Hasan Ak³n,Selman Ugu 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.5
We study the phase diagrams for the Potts model on the Bethe lattice with competing nearest-neighbor interactions J1 and ternary interactions J_p and J_t: A_t vanishing temperature, the phase diagram is fully determined for all values and signs of J_p = J_1 and J_t = J_1; in particular, we show that the phase diagrams contain ferromagnetic, paramagnetic and < 2 > phases only; <i>i.e.</i>, the set of modulated phases consists of the < 2 > phase only for J_1 > 0 and J_p = J_1 < 0: We verify that values of T = J_1 in the very narrow strip -0.11 < T = J_1 < 0 with -J_p = J_1 < 0 favor the modulated phase, which is either a commensurate phase with a very large period or an incommensurate phase. The transition lines are obtained from stability conditions, and characteristic points in the phase diagram are analyzed by using numerical iterations. Also the wavevectors versus temperature are plotted for some critical points in the modulated phases.
