Magnetization and Lyapunov exponents on a kagome chain with multi-site exchange interaction

N. Ananikian, L. Ananikyan, R. Artuso +1

The Ising approximation of the Heisenberg model in a strong magnetic field, with two, three and six spin exchange interactions is studied on a kagome chain. The kagome chain can be…

Arnold Tongues and Feigenbaum Exponents of the Rational Mapping for Q-state Potts Model on Recursive Lattice: Q<2

L. N. Ananikyan, N. S. Ananikian, L. A. Chakhmakhchyan

We considered Q-state Potts model on Bethe lattice in presence of external magnetic field for Q<2 by means of recursion relation technique. This allows to study the phase transitio…

Exactly solvable mixed-spin Ising-Heisenberg diamond chain with the biquadratic interactions and single-ion anisotropy

Onofre Rojas, S. M. de Souza, Vadim Ohanyan +1

An exactly solvable variant of mixed spin-(1/2,1) Ising-Heisenberg diamond chain is considered. Vertical spin-1 dimers are taken as quantum ones with Heisenberg bilinear and biquad…

Exactly solvable Ising--Heisenberg chain with triangular XXZ-Heisenberg plaquettes

Diana Antonosyan, Stefano Bellucci, Vadim Ohanyan

A mixed Ising-Heisenberg spin system consisting of triangular XXZ-Heisenberg spin clusters assembled into a chain by alternating with Ising spins interacting to all three spins in…
