Luttinger liquid and polaronic effects in electron transport through a molecular transistor
Electron transport through a single-level quantum weakly dot coupled to Luttinger liquid leads is considered in the master equation approach. It is shown that for a weak or moderately strong interaction the differential conductance demonstrates resonant-like behavior as a function of bias and gate...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Electron transport through a single-level quantum weakly dot coupled to Luttinger liquid leads is considered
in the master equation approach. It is shown that for a weak or moderately strong interaction the differential
conductance demonstrates resonant-like behavior as a function of bias and gate voltages. The inelastic
channels associated with vibron-assisted electron tunnelling can even dominate electron transport for a certain
region of interaction strength. In the limit of strong interaction resonant behavior disappears and the differential
conductance scales as a power low on temperature (linear regime) or on bias voltage (nonlinear regime). |
