Quantum decoherence of interacting electrons in arrays of quantum dots and diffusive conductors

“…We observe that for D 10 cm 2 /s the data points clearly follow the scaling (74). Practically all data points remain within the strip between the two lines corresponding to Eq.…”

“…Hence, the dependence of τϕ0 on D for strongly disordered or granular conductors ( 75) is it qualitatively different from that for sufficiently clean metals (74).…”

“…Within that approach local properties of the model could not be fully defined. For this reason in the corresponding integrals in [37,38,39] we could not avoid using an effective high frequency cutoff procedure which yields the correct leading dependence τϕ0 ∝ D 3 and it only does not allow to recover an additional logarithmic dependence on D in (74). Our present approach is divergence-free and, hence, it does not require any cutoffs.…”

“…On the other hand, for more disordered conductors with D 10 cm 2 /s the data are consistent with the scaling (75) obtained within the model (b). We would like to emphasize that theoretical curves (74) and (75) are presented in Fig. 6 without any additional fit parameters except for a geometry factor γ for the first dependence and the value gc ≈ 150 for the second one.…”

“…7 again clearly support the scaling of τϕ0 with D (74) due to electron-electron interactions. Practically all data points are now located inbetween the solid and dashed lines which indicate the dependence (74) with respectively γ = 0.2 and γ = 0.5. We cannot exclude that the remaining scatter among the data points with similar values of D -to a certain extent -may be due to relatively small amount of magnetic impurities possibly residing in some samples.…”
