Tuning of the spin-orbit interaction in a quantum dot by an in-plane magnetic field
M. P. Nowak, B. Szafran, F. M. Peeters +2
Using an exact diagonalization approach we show that one- and two-electron InAs quantum dots exhibit avoided crossing in the energy spectra that are induced by the spin-orbit coupl…
Magnetic forces and localized resonances in electron transfer through quantum rings
M. R. Poniedziałek, B. Szafran
We study the current flow through semiconductor quantum rings. In high magnetic field the current is usually injected to the arm of the ring preferred by classical magnetic forces.…
Tuning Fano resonances by magnetic forces for electron transport through a quantum wire side-coupled to a quantum ring
B. Szafran, M. R. Poniedziałek
We consider electron transport in a quantum wire with a side-coupled quantum ring in a two-dimensional model that accounts for a finite width of the channels. We use the finite dif…
Violation of Onsager symmetry for a ballistic channel Coulomb coupled to a quantum ring
B. Szafran, M. R. Poniedzialek, F. M. Peeters
We investigate a scattering of electron which is injected individually into an empty ballistic channel containing a cavity that is Coulomb coupled to a quantum ring charged with a…
Few-electron artificial molecules formed by laterally coupled quantum rings
T. Chwiej, B. Szafran
We study the artificial molecular states formed in laterally coupled double semiconductor nanorings by systems containing one, two and three electrons. An interplay of the interrin…
Gated combo nanodevice for sequential operations on single electron spin
S. Bednarek, B. Szafran
An idea for a nanodevice in which an arbitrary sequence of three basic quantum single qubit gates - negation, Hadamard and phase shift - can be performed on a single electron spin.…
