Locations of multicritical points for spin glasses on regular lattices
Masayuki Ohzeki
We present an analysis leading to precise locations of the multicritical points for spin glasses on regular lattices. The conventional technique for determination of the location o…
Multicritical points for the spin glass models on hierarchical lattices
Masayuki Ohzeki, Hidetoshi Nishimori, A. Nihat Berker
The locations of multicritical points on many hierarchical lattices are numerically investigated by the renormalization group analysis. The results are compared with an analytical…
Multicritical Points of Potts Spin Glasses on the Triangular Lattice
Masayuki Ohzeki
We predict the locations of several multicritical points of the Potts spin glass model on the triangular lattice. In particular, continuous multicritical lines, which consist of mu…
Internal Energy of the Potts model on the Triangular Lattice with Two- and Three-body Interactions
Masayuki Ohzeki, Hidetoshi Nishimori
We calculate the internal energy of the Potts model on the triangular lattice with two- and three-body interactions at the transition point satisfying certain conditions for coupli…
Location of the Multicritical Point for the Ising Spin Glass on the Triangular and Hexagonal Lattices
Hidetoshi Nishimori, Masayuki Ohzeki
A conjecture is given for the exact location of the multicritical point in the phase diagram of the +/- J Ising model on the triangular lattice. The result p_c=0.8358058 agrees wel…
