Josephson transport through a single molecule or carbon nanotube is considered in the presence of a local vibrational mode coupled to the electronic charge. The ground-state solution is obtained exactly in the limit of a large superconducting gap and is extended by variational analysis. The Josephson current induces squeezing of the phonon mode, which is controlled by the superconducting phase difference and by the junction asymmetry. Optical probes of nonclassical phonon states are briefly… Expand

Sub-Poissonian phononic population in a nanoelectromechanical system
The properties of the phononic distribution of a mechanical oscillator coupled to a single-electron transistor are investigated in the sequential tunnelling regime. It is shown that for not tooExpand
Polaronic effects induced by non-equilibrium vibrons in a single-molecule transistor
Current-voltage characteristics of a single-electron transistor with a vibrating quantum dot were calculated assuming vibrons to be in a coherent (non-equilibrium) state. For a large amplitude ofExpand
Nanoelectromechanics of superconducting weak links (Review Article)
Nanoelectromechanical effects in superconducting weak links are considered. Three different superconducting devices are studied: (i) a single-Cooper-pair transistor, (ii) a transparent SNS junction,Expand
Self-consistent description of Andreev bound states in Josephson quantum dot devices
We develop a general perturbative framework based on a superconducting atomic limit for the description of Andreev bound states (ABS) in interacting quantum dots connected to superconducting leads. AExpand
Manifestation of polaronic effects in Josephson currents
Polaronic effects on the Josephson current through a vibrating quantum dot are considered. In the regime of strong electron–vibron interactions they lead to a power-law suppression of the criticalExpand
Temperature effect in the conductance of hydrogen molecule
We present a many-body calculation for the conductance of a conducting bridge of a simple hydrogen molecule between Pt electrodes. The experimental results showed that the conductance G=dI/dV has theExpand
Superconducting properties of carbon nanotubes
Abstract Metallic single wall carbon nanotubes have attracted much interest as 1D quantum wires combining a low carrier density and a high mobility. It was believed for a long time that lowExpand

Metallic single wall carbon nanotubes have attracted considerable interest as 1D quantum wires combining a low carrier density and a high mobility. It was believed for a long time that lowExpand
Bistability and displacement fluctuations in a quantum nanomechanical oscillator
Remarkable features have been predicted for the mechanical fluctuations at the bistability transition of a classical oscillator coupled capacitively to a quantum dot [Phys. Rev. Lett. 115, 206802Expand
Variational study of a two-level system coupled to a harmonic oscillator in an ultrastrong-coupling regime
The nonclassical behavior of a two-level system coupled to a harmonic oscillator is investigated in the ultrastrong coupling regime. We revisit the variational solution of the ground state and findExpand
