Summary: | It is in our interest to investigate the effect of the third nearest-neighbour binary
interaction to the phase diagrams of the Potts model on a Cayley tree. Therefore, we generate
and analyse the phase diagrams of the Potts model, considering prolonged competing binary
interaction J2 and J3 on the same branch of the Cayley tree up to the third nearest-neighbour
generations. We derive the recurrence system of equations while taking into account some
ranges of competing parameters. We carry out a numerical procedure by applying several
stability conditions and characteristic points into the iteration scheme. For some non-zero
parameter J3, we found the additional phases of period 5, 6, 9, and 11, with the ferromagnetic,
antiphase, paramagnetic, antiferromagnetic and modulated phase. For the modulated phase,
we further study the existence of phases with period larger than 12 by conducting a numerical
analysis on the variation of wavevector and Lyapunov exponent. |
