Ground-state cooling of a suspended nanowire through inelastic macroscopic quantum tunneling in a current-biased Josephson junction
Gustav Sonne, Leonid Y. Gorelik
We demonstrate that a suspended nanowire forming a weak link between two superconductors can be cooled to its motional ground state by a supercurrent flow. The predicted cooling me…
Voltage-driven superconducting weak link as a refrigerator for cooling of nanomechanical vibrations
Gustav Sonne, Milton E. Peña-Aza, Leonid Y. Gorelik +2
We consider a new type of cooling mechanism for a suspended nanowire acting as a weak link between two superconductive electrodes. By applying a bias voltage over the system, we sh…
Cooling of a suspended nanowire by an AC Josephson current flow
Gustav Sonne, Milton E. Peña-Aza, Leonid Y. Gorelik +2
We consider a nanoelectromechanical Josephson junction, where a suspended nanowire serves as a superconducting weak link, and show that an applied DC bias voltage an result in supp…
Non-Equilibrium and Quantum Coherent Phenomena in the Electromechanics of Suspended Nanowires
Robert I. Shekhter, Fabio Santandrea, Gustav Sonne +2
Strong coupling between electronic and mechanical degrees of freedom is a basic requirement for the operation of any nanoelectromechanical device. In this Review we consider such d…
Temperature independent current deficit due to induced quantum nanowire vibrations
Gustav Sonne
We consider electronic transport through a suspended voltage-biased nanowire. By coupling the tunneling current to a transverse magnetic field, vibrational modes of the wire are ex…
