Coupled multiple-mode theory for pairing mechanism in iron based superconductors
M. N. Kiselev, D. V. Efremov, S. L. Drechsler +2
We investigate the interplay between the magnetic and the superconducting degrees of freedom in unconventional multi-band superconductors such as iron pnictides. For this purpose a…
Shuttle-promoted nano-mechanical current switch
Taegeun Song, Leonid Y. Gorelik, Robert I. Shekhter +2
We investigate electron shuttling in three-terminal nanoelectromechanocal device built on a movable metallic rod oscillating between two drains. The device shows a double-well shap…
Self-sustained oscillations in nanoelectromechanical systems induced by Kondo resonance
Taegeun Song, Mikhail N. Kiselev, Konstantin Kikoin +2
We investigate instability and dynamical properties of nanoelectromechanical systems represented by a single-electron device containing movable quantum dot attached to a vibrating…
SU(3) Landau - Zener Interferometry
M. N. Kiselev, K. Kikoin, M. B. Kenmoe
We consider a general theory of Landau-Zener transitions in a three-level system. Based on a classification of three level crossings we express the Landau - Zener Hamiltonians in t…
The dual nature of As-vacancies in LaFeAsO-derived superconductors: magnetic moment formation while preserving superconductivity
Konstantin Kikoin, Stefan-Ludwig Drechsler, Jiri Malek +1
As-vacancies (V_As) in La-1111-systems, which are nominally non-magnetic defects, are shown to create in their vicinity by symmetry ferromagnetically oriented local magnetic moment…
The Nature of the magnetism-promoting hole state in the prototype magnetic semiconductor GaAs: Mn
V. Fleurov, K. Kikoin, A. Zunger
Recent experiments [1] suggest that the ferromagnetism (FM) in GaAs: Mn is determined by the impurity band rather than holes in the valence band. We discuss here the physical mecha…
