Mechanical systems are ideal candidates for studying quantum behavior of macroscopic
objects. To this end, a mechanical resonator has to be cooled to its ground state and its …

Transport of electrons in a single molecule junction is the simplest problem in the general
subject area of molecular electronics. In the past few years, this area has been extended to …

Current-voltage characteristics of suspended single-wall carbon nanotube quantum dots
show a series of steps equally spaced in voltage. The energy scale of this harmonic, low …

Mechanical oscillators have been demonstrated with very high quality factors over a wide
range of frequencies. They also couple to a wide variety of fields and forces, making them …

Heating and heat conduction in molecular junctions are considered within a general
nonequilibrium Green's function formalism. We obtain a unified description of heating in …

At present, metal–molecular tunnel junctions are recognized as important active elements in
molecular electronics. This gives a strong motivation to explore physical mechanisms …

We develop methods for calculating the zero-frequency noise for quantum shuttles, ie,
nanoelectromechanical devices where the mechanical motion is quantized. As a model …

While heating of a current carrying Ohmic conductors is an obvious consequence of the
diffusive nature of the conduction in such systems, current-induced cooling has been …

Using a quantum-noise approach, we discuss the physics of both normal metal and
superconducting single-electron transistors (SSETs) coupled to mechanical resonators …

We propose a spectroscopic approach to probe tiny vibrations of a nanomechanical
resonator (NAMR), which may reveal classical or quantum behavior depending on the …
