Double quantum dot as a spin rotator
Konstantin Kikoin, Yshai Avishai
It is shown that the low-energy spin states of double quantum dots (DQD) with even electron occupation number possess the symmetry SO(4) similar to that of a rigid rotator fami…
Localized states in 2D semiconductors doped with magnetic impurities in quantizing magnetic field
P. Dahan, V. Fleurov, K. Kikoin +1
A theory of magnetic impurities in a 2D electron gas quantized by a strong magnetic field is formulated in terms of Friedel-Anderson theory of resonance impurity scattering. It is…
Kondo tunneling tgrough a biased quantum dot
Yshai Avishai, Konstantin Kikoin
Electron tunneling through a system formed by two coupled quantum dots in a parallel geometry is considered within a generalized Anderson model. The dots are assumed to have nearly…
Bound spin-excitons in two-dimensional electron gas
V. Fleurov, K. Kikoin
A theory of the spin exciton capture by a magnetic impurity in a 2D electron gas is developed. We consider the resonance model for electron scattering by a transition metal impurit…
