Daydreaming algorithm for Biased Patterns
Mikiya Doi, Masayuki Ohzeki, Federico Ricci-Tersenghi
The \emph{Daydreaming} algorithm has been recently proposed in Ref.~\cite{Serricchio2025} as a learning rule that simultaneously reinforces stored patterns and suppresses spurious…
Impact of Stealthy Hyperuniform Magnetic Impurity Configurations on Bulk Magnetism in a Two-dimensional Heisenberg Model
K. Asakura, K. Yamamoto, A. Koga
We investigate an antiferromagnetic quantum Heisenberg model on a square lattice with high-spin magnetic impurities to clarify how random and stealthy hyperuniform impurity configu…
Exact mapping of a spin glass with correlated disorder to the pure Ising model
Hidetoshi Nishimori
We introduce an Ising spin-glass model with correlated disorder which continuously interpolates between the pure ferromagnetic Ising model and the Edwards-Anderson model with symme…
Temperature chaos as a logical consequence of the reentrant transition in spin glasses
Hidetoshi Nishimori, Masayuki Ohzeki, Manaka Okuyama
Temperature chaos is a striking phenomenon in spin glasses, where even slight changes in temperature lead to a complete reconfiguration of the spin state. Another intriguing effect…
Instability of the ferromagnetic phase under random fields in an Ising spin glass with correlated disorder
Hidetoshi Nishimori
It is well established that the ferromagnetic phase remains stable under random magnetic fields in three and higher dimensions for the ferromagnetic Ising model and the Edwards-And…
Anomalous distribution of magnetization in an Ising spin glass with correlated disorder
Hidetoshi Nishimori
The effect of correlations in disorder variables is a largely unexplored topic in spin glass theory. We study this problem through a specific example of correlated disorder introdu…
Replica bound for Ising spin glass models in one dimension
Manaka Okuyama, Masayuki Ohzeki
The interpolation method is a powerful tool for rigorous analysis of mean-field spin glass models, both with and without dilution. In this study, we show that the interpolation met…
Free energy equivalence between mean-field models and nonsparsely diluted mean-field models
Manaka Okuyama, Masayuki Ohzeki
We studied nonsparsely diluted mean-field models that differ from sparsely diluted mean-field models, such as the Viana--Bray model. When the existence probability of each edge fol…
