“…still applies, if one assumed that the protons under confinement would walk subdiffusively, their root mean-squared displacement, denoted by l rmsq had to cease upon increasing time t, such as l rmsq ≡ l rmsq (t) ∼ t µ with 0 < µ < 1/2. In other words, the value of D H + should be assumed t-dependent, causing D H + (t) ∼ t 2µ−1 to decrease in an algebraic way [31]. Another option that one would not discard is the logarithmic (even Sinai-type or billiard-involving) diffusion which also decelerates in its tempo when compared with its standard counterpart [32].…”
