  • Nanomechanics of a magnetic shuttle device 
    Kulinich, S.I.; Gorelik, L.Y.; Parafilo, A.V.; Shekhter, R.I.; Park, Y.W.; Jonson, M. (Физика низких температур, 2014)
    We show that self sustained mechanical vibrations in a model magnetic shuttle device can be driven by both the charge and the spin accumulated on the movable central island of the device. Different scenarios for how spin- ...
  • Novel laser based on magnetic tunneling 
    Kadigrobov, A.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2005)
    A new principle for a compact spin-based solid-state laser is proposed. It operates in the 1–100 THz regime, which is difficult to reach with small size lasers. Spin-flip processes in ferromagnetic conductors form a basis ...
  • Photon generation in ferromagnetic point contacts 
    Kadigrobov, A.M.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2012)
    We show theoretically that a significant spin accumulation can occur in electric point contacts between two ferromagnetic electrodes with different magnetizations. Under appropriate conditions an inverse population ...
  • Photo-spintronics of spin-orbit active electric weak links 
    Shekhter, R.I.; Entin-Wohlman, O.; Jonson, M.; Aharony, A. (Физика низких температур, 2017)
    We show that a carbon nanotube can serve as a functional electric weak link performing photo-spintronic transduction. A spin current, facilitated by strong spin-orbit interactions in the nanotube and not accompanied by a ...
  • Pumping of energy into a mesoscopic ring: Exactly solvable model 
    Gorelik, L.; Kulinich, S.; Shekhter, R.I.; Jonson, M.; Galperin, Yu. (Физика низких температур, 1998)
    We consider the energy stored in a one-dimensional ballistic ring with a barrier subjected to a linearly time-dependent magnetic flux. An exact analytical solution for the quantum dynamics of electrons in the ring is found ...
  • Quantum size effect and interlayer electron tunneling in metal-semiconductor superlattices 
    Fogel, N.Ya.; Shekhter, R.I.; Slutskin, A.A.; Kovtun, H.A. (Физика низких температур, 1999)
    A new type of quantum size effect in metal-semiconductor superlattices is predicted. Giant oscillations of the transverse tunnel conductivity arise if size quantization of the electron spectrum in the metal layers takes ...
  • Rashba proximity states in superconducting tunnel junctions 
    Entin-Wohlman, O.; Shekhter, R.I.; Jonson, M.; Aharony, A. (Физика низких температур, 2018)
    We consider a new kind of superconducting proximity effect created by the tunneling of “spin split” Cooper pairs between two conventional superconductors connected by a normal conductor containing a quantum dot. The ...
  • Rashba spin-splitting of single electrons and Cooper pairs 
    Shekhter, R.I.; Entin-Wohlman, O.; Jonson, M.; Aharony, A. (Физика низких температур, 2017)
    Electric weak links, the term used for those parts of an electrical circuit that provide most of the resistance against the flow of an electrical current, are important elements of many nanodevices. Quantum dots, nanowires ...
  • Resonant tunneling of electrons in quantum wires 
    Krive, I.V.; Palevski, A.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2010)
    We considered resonant electron tunneling in various nanostructures including single wall carbon nanotubes, molecular transistors and quantum wires formed in two-dimensional electron gas. The review starts with a textbook ...
  • Triplet superconducting proximity effect in nonhomogeneous magnetic materials 
    Kadigrobov, A.; Shekhter, R.I.; Jonson, M. (Физика низких температур, 2001)
    We show that quantum spin fluctuations in inhomogeneous conducting ferromagnets drastically affect the Andreev reflection of electrons and holes at a ferromagnet- superconductor interface. As a result, a strong ...
