Stretched exponential relaxation arising from a continuous sum of exponential decays
Stretched exponential relaxation of a quantity $n$ versus time $t$ according to $n={n}_{0}\phantom{\rule{0.2em}{0ex}}\mathrm{exp}[\ensuremath{-}{({\ensuremath{\lambda}}^{*}t)}^{\ensuremath{\beta}}]$ is ubiquitous in many research fields, where ${\ensuremath{\lambda}}^{*}$ is a characteristic relaxation rate and the stretching exponent $\ensuremath{\beta}$ is in the range $0<\ensuremath{\beta}<1$. Here we consider systems in which stretched exponential relaxation arises from global relaxation of …
