Numerical results for ground states of spin glasses on Bethe lattices
The average ground state energy and entropy for ±J spin glasses on Bethe lattices of connectivities k + 1 = 3 . . . , 26 at T = 0 are approximated numerically. To obtain sufficient accuracy for large system sizes (up to n = 2), the Extremal Optimization heuristic is employed which provides high-quality results not only for the ground state energies per spin ek+1 but also for their entropies sk+...
متن کاملSpin systems on hypercubic Bethe lattices: A Bethe-Peierls approach
We study spin systems on Bethe lattices constructed from ddimensional hypercubes. Although these lattices are not tree-like, and therefore closer to real cubic lattices than Bethe lattices or regular random graphs, one can still use the Bethe-Peierls method to derive exact equations for the magnetization and other thermodynamic quantities. We compute phase diagrams for ferromagnetic Ising model...
متن کاملMean-field theory of spin-glasses with finite coordination number.
The mean-field theory of dilute spin-glasses is studied in the limit where the average coordination number is finite. The zero-temperature phase diagram is calculated and the relationship between the spin-glass phase and the percolation transition is discussed. The present formalism is applicable also to graph optimization problems. The mean-field theory (MFT) of spin-glasses usually refers to ...
متن کاملGlass models on Bethe lattices
We consider " lattice glass models " in which each site can be occupied by at most one particle, and any particle may have at most ℓ occupied nearest neighbors. Using the cavity method for locally tree-like lattices, we derive the phase diagram, with a particular focus on the vitreous phase and the highest packing limit. We also study the energy landscape via the configurational entropy, and di...
متن کاملOn the number of metastable states in spin glasses
In this letter, we show that the formulae of Bray and Moore for the average logarithm of the number of metastable states in spin glasses can be obtained by calculating the partition function with m coupled replicas with the symmetry among these explicitly broken according to a generalization of the ‘two-group’ ansatz. This equivalence allows us to find solutions of the bm equations where the lo...
