Potts model with next-nearest-neighbor ternary interactions on an arbitrary-order Cayley tree
We study the phase diagrams for the Potts model with restricted competing nearest-neighbor interactions J1 and ternary interactions Jpt on a Cayley tree of arbitrary order k. At vanishing temperature, the phase diagram is fully determined for all values and signs of Jpt/J1 and T/J1. The phase diag...

| Summary: | We study the phase diagrams for the Potts model with restricted competing nearest-neighbor interactions J1 and
ternary interactions Jpt on a Cayley tree of arbitrary order k. At vanishing temperature, the phase diagram is fully
determined for all values and signs of Jpt/J1 and T/J1. The phase diagrams are obtained from stability conditions,
and characteristic points in the iteration scheme are numerically analyzed. The wavevectors versus temperature are
plotted for some critical points in the modulated phases. Then, we using the Lyapunov exponent to verify the
stability of the periods.
