标题： Temperature chaos as a logical consequence of reentrant transition in spin glasses

摘要： 温度混沌是自旋玻璃中的一个显著现象，其中温度的微小变化会导致自旋状态的完全重新配置。 另一个引人入胜的现象是再进入转变，在这种转变中，降低温度会使系统从铁磁相转变为有序度较低的自旋玻璃或顺磁相。 在本文中，我们通过引入一种广义公式来揭示这些看似无关现象之间的意外联系，该公式考虑了无序变量之间的相关性，在有限维的爱德华-安德森自旋玻璃模型中。 假设在有限温度下存在自旋玻璃相，我们证明温度混沌是爱德华-安德森模型中再进入现象的逻辑结果。 我们的发现揭示了再进入和温度混沌之间以前隐藏的数学结构，为自旋玻璃物理提供了一种超越平均场理论的新视角。 显示英文摘要

摘要： 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 is the reentrant transition, in which lowering the temperature drives the system from a ferromagnetic phase into a less ordered spin-glass or paramagnetic phase. In the present paper, we reveal an unexpected connection between these seemingly unrelated phenomena in the finite-dimensional Edwards-Anderson model of spin glasses by introducing a generalized formulation that incorporates correlations among disorder variables. Assuming the existence of a spin glass phase at finite temperature, we establish that temperature chaos arises as a logical consequence of reentrance in the Edwards-Anderson model. Our findings uncover a previously hidden mathematical structure relating reentrance and temperature chaos, offering a new perspective on the physics of spin glasses beyond the mean-field theory.
