Energy dependence of the real (top panel) and imaginary (bottom panel) parts of . The curves are plotted assuming , , , (dashed lines), and (solid lines) at .
The renormalized electron transmission function vs energy. The curves are plotted for , , (dashed lines), and (solid lines). The constant equals (top panel) and (bottom panel).
The current-voltage characteristics plotted for , , , , (left panel), and (right panel) at (dashed lines) and (solid lines).
Arrhenius plot of the peak value of the electron transmission function for , , , and . The solid line is plotted assuming the indirect coupling of the bridge to the phonon bath [Eqs. (11) and (25)]. The dashed line is plotted assuming that the bridge is directly coupled to the phonons [Eq. (29)].
