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...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| 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.
