We investigate the relationship between two experimental sets of data related to dynamical heterogeneity, the coefficient alpha of 1/f(alpha) dipolar noise derived from the nonexponentiality of the dielectric or magnetic response near and above the mean relaxation time, and the range Delta(z) of the relaxation times. We find that in different classes of glasses, including spin and proton glasses, relaxor materials, and glass-forming liquids, this relationship exhibits the same trend.
我们研究了与动力学非均匀性相关的两组实验数据之间的关系，即从平均弛豫时间附近及以上的介电或磁响应的非指数性得出的1/f(α)偶极噪声的系数α，以及弛豫时间的范围Δ(z)。我们发现，在不同类型的玻璃中，包括自旋玻璃和质子玻璃、弛豫体材料以及玻璃形成液体，这种关系呈现出相同的趋势。
