Spiral states, first-order transitions and specific heat multipeak phenomenon in J 1 - J 2 - J 3 Ising model: A Wang-Landau algorithm study
This study used a numerical Wang-Landau algorithm to investigate a frustrated J1-J2-J3 Ising model on a honeycomb lattice. It found that the armchair and spiral phases coexist, resulting in 20-fold degeneracy. The research also identified first-order phase transitions and specific heat multipeak behavior under certain interaction strengths, providing new insights into phase nature.
