Название: On the Ground-State Threshold in Random Two-Dimensional Ising +/-J Models
Автор: Bendisch J.
Journal of Statistical Physics, Vol. 67, Nos. 5/6, 1992. p. 1209-1217.
For square, triangular, and for hexagonal lattices there is numerical and theoretical support that the ground-state threshold p_c between ferro- and paramagnetism in random 2D Ising +/-J models, with p as the concentration of antiferromagnetic bonds, is identical to p* which is characterized by minimal matching properties of frustrated plaquettes...
