Nanoelectromechanics of superconducting weak links

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, and (iii) a single-level
 quantum dot coupled to superconducting electrodes. The ele...

Description
Summary: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, and (iii) a single-level
 quantum dot coupled to superconducting electrodes. The electromechanical coupling is due to electrostatic or
 magnetomotive forces acting on a movable part of the device. It is demonstrated that depending on the frequency
 of mechanical vibrations the electromechanical coupling could either suppress or enhance the Josephson current.
 Nonequilibrium effects associated with cooling of the vibrational subsystem or pumping energy into it at low
 bias voltages are discussed.
