Tahir M, MacKinnon A, Time-dependent transport via a quantum shuttle

We present a theoretical study of time-dependent transport via a quantumshuttle within the non-equilibrium Green's function technique. An arbitraryvoltage is applied to the tunnel junction and electrons in the leads areconsidered to be at zero temperature. The transient and the steady statebehavior of the system is considered here in order to explore the quantumdynamics of the shuttle device as a function of time and applied bias. Theproperties of the phonon distribution of the oscillating dot coupled to theelectrons are investigated using a non-perturbative approach. We derive arelation for the oscillator momentum charge density correlation function whichis an interesting physical example for the visualization of shuttlingphenomenon. We consider the crossover between the tunneling and shuttlingregimes for different values of the key parameters as a function of appliedbias and time. We also consider the energy transferred from the electrons tothe oscillating dot as a function of time. This will provide useful insight forthe design of experiments aimed at studying the quantum behavior of a shuttlingdevice.

Tahir M, MacKinnon A, Current noise of a resonant tunnel junction coupled to a nanomechanical oscillator

We present a theoretical study of current noise of a resonant tunnel junctioncoupled to a nanomechanical oscillator within the non-equilibrium Green'sfunction technique. An arbitrary voltage is applied to the tunnel junction andelectrons in the leads are considered to be at zero temperature. The propertiesof the phonon distribution of the nanomechanical oscillator strongly coupled tothe electrons on the dot are investigated using a non-perturbative approach. Ananalytical calculations and numerical results for the current-voltage, shotnoise and the corresponding Fano factor as a function of applied bias showsignificant features of the nanomechanical oscillator coupling dynamics. Thiswill provide useful insight for the design of experiments aimed at studying thequantum behavior of an oscillator.
