The Monte Carlo method can also compute average values that are used to compute thermodynamic quantities like magnetization, spin-spin correlation, correlation lengths, and The Monte Carlo approach [15, 16], which permits rough estimations, is mostly used in this kind of algorithms. However, algorithms [17-20] that make it possible to exactly calculate the free In addition to the isotropic Heisenberg model, extensive work has been done on the ground state phase dia-gram of the spin-1/2 frustrated honeycomb XY model.
