Abstract
Unbiased samples of ground states were generated for the short-range Ising spin glass with J(ij) = +/-1, in three dimensions. Clustering the ground states revealed their hierarchical structure, which is explained by correlated spin domains, serving as cores for macroscopic zero energy "excitations."
摘要
针对三维空间中具有(J(ij) = +/-1)的短程伊辛自旋玻璃，生成了基态的无偏样本。对基态进行聚类揭示了它们的层次结构，这可以由相关自旋域来解释，这些自旋域作为宏观零能量“激发”的核心。
