FIG. 1.

Polaron velocity for the case of ordered coupling under the electric field strength E = 0.3 mV/Å and 0.5 mV/Å.

FIG. 2.

Mean polaron velocities 〈v〉 versus σ t are depicted for t = 0.04 eV and 0.05 eV under different electric field, (a) E = 0.5 mV/Å, (b) E = 0.9 mV/Å, (c) E = 1.3 mV/Å, and (d) E = 1.7 mV/Å.

FIG. 3.

Time evolution of the (a)–(c) charge density and (d) polaron center at t = 0.05 eV under the field E = 1.7 mV/Å. (a) σ t = 0.01 eV, (b) σ t = 0.03 eV, and (c) σ t = 0.05 eV.

Snapshots of charge distribution at various times for the same parameter shown in Fig. 3.

Image of FIG. 5.
FIG. 5.

Polaron velocity versus σ t and the seed of random numbers under the field E = 0.5 mV/Å. Three values of t are chosen, i.e., 0.04 eV, 0.05 eV, and 0.06 eV.

Image of FIG. 6.
FIG. 6.

Time evolution of the polaron center for various values of σ t and various groups of random numbers at E = 0.5 mV/Å, t = 0.1 eV and 0.2 eV. (a) σ t = 0.01 eV, (b) σ t = 0.03 eV, (c) σ t = 0.06 eV, and (d) σ t = 0.09 eV.

FIG. 8.

The error analysis for statistical averages of velocity is carried out. The mean velocities 〈v〉 versus σ t are given for different seed number (10, 20, 30, and 40) under E = 0.5 mV/Å, t = 0.2 eV.

FIG. 9.

Mean polaron velocities 〈v〉 versus σ t are depicted for t = 0.2 eV under different electric field (0.3 mV/Å−1.3 mV/Å).
