Energy pumping in a quantum nanoelectromechanical system
Fully quantized mechanical motion of a single-level quantum coupled to two voltage biased electronic leads is studied. It is found that there are two different regimes depending on the applied voltage. If the bias voltage is below a certain threshold (which depends on the energy of the vibrationa...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Fully quantized mechanical motion of a single-level quantum coupled to two voltage biased
electronic leads is studied. It is found that there are two different regimes depending on the applied
voltage. If the bias voltage is below a certain threshold (which depends on the energy of the
vibrational quanta) the mechanical subsystem is characterized by a low level of excitation. Above
a threshold the energy accumulated in the mechanical degree of freedom dramatically increases.
The distribution function for the energy level population and the current through the system in
this regime is calculated. |
