Phase diagrams of soluble multi-spin glass models

چکیده
We include p-spin interactions in a spherical version of a soluble mean-field spinglass model proposed by van Hemmen. Due to the simplicity of the solutions, which do not require the use of the replica trick, we are able to carry out a detailed investigation of a number of special situations. For p ≥ 3, there appear first-order transitions between the paramagnetic and the ordered phases. In the presence of additional ferromagnetic interactions, we show that there is no stable mixed phase, with both ferromagnetic and spin-glass properties.

متن کاملOdd q-state clock spin-glass models in three dimensions, asymmetric phase diagrams, and multiple algebraically ordered phases.
Distinctive orderings and phase diagram structures are found, from renormalization-group theory, for odd q-state clock spin-glass models in d=3 dimensions. These models exhibit asymmetric phase diagrams, as is also the case for quantum Heisenberg spin-glass models. No finite-temperature spin-glass phase occurs. For all odd q≥5, algebraically ordered antiferromagnetic phases occur. One such phas...
متن کاملGround-State Phase Diagrams of the Two-Dimensional Quantum Heisenberg Spin Glass Models
Ground-state properties of the two-dimensional S = 1/2 random Heisenberg models are investigated by the exact-diagonalization method. The phase diagram of the bondrandom model (the ±J model) is the same as that of the corresponding Ising spin glass model, in spite of quantum fluctuation. In the site-random model, the spin glass phase exists at least in the ferro-rich case. In comparison with th...
متن کاملCritical Behavior of the Bethe Lattice Spin Glass
We present results of a rigorous analysis of the k J king spin glass on the Bethe lattice with uncorrelated boundary conditions. We derive phase diagrams as functions of temperature 'us. percentage of ferromagnetic bonds, and, when half of the bonds are ferromagnetic, temperature 'us. external field. Critical exponents are also determined. Using bifurcation theory, we establish the existence of...
متن کاملTwo-cycles in spin-systems: multi-state Ising-type ferromagnets
Abstract. Hamiltonians for general multi-state spin-glass systems with Ising symmetry are derived for both sequential and synchronous updating of the spins. The possibly different behaviour caused by the way of updating is studied in detail for the (anti)-ferromagnetic version of the models, which can be solved analytically without any approximation, both thermodynamically via a free-energy cal...
