标题： Instability of the ferromagnetic phase under random fields in an Ising spin glass with correlated disorder

摘要： 众所周知，在三个及以上维度中，对于无序变量不相关的情况下，铁磁相在随机磁场下对于铁磁伊辛模型和爱德华-安德森自旋玻璃模型是稳定的。 在本研究中，我们研究了一个具有相关无序的伊辛自旋玻璃，并证明了只要在相同晶格上的爱德华-安德森模型存在磁场所导致的混沌，铁磁相在任何维度下都会在随机场中变得不稳定。 此外，我们还表明，这种不稳定性也可以归因于无序（键）混沌。 我们进一步认为，只要在相同晶格上的爱德华-安德森模型在磁场下表现出自旋玻璃相，具有相关无序的模型即使在存在对称破缺场的情况下仍会保持铁磁相。 这些结果强调了无序中空间相关性的重要影响。 显示英文摘要

摘要： 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-Anderson model of spin glasses without correlation in the disorder variables. In this study, we investigate an Ising spin glass with correlated disorder and demonstrate that the ferromagnetic phase becomes unstable under random fields in any dimension, provided that magnetic field chaos exists in the Edwards-Anderson model on the same lattice. Additionally, we show that this instability can also be attributed to disorder (bond) chaos. We further argue that the model with correlated disorder remains in the ferromagnetic phase even in the presence of symmetry-breaking fields, as long as the Edwards-Anderson model on the same lattice exhibits a spin glass phase under a magnetic field. These results underscore the profound impact of spatial correlations in the disorder.
