Manipulating spin and charge in magnetic semiconductors usingsuperconducting vortices
Mona Berciu, Tatiana G. Rappoport, B. Janko
The continuous need for miniaturization and increase in device speed exerts pressureon the electronics industry to explore new avenues of information processing. One possibility is…
Theory of Manganese-Manganese interaction in GaMnAs
P. Redlinski, G. Zarand, B. Janko
We investigate the interaction of two Mn ions in the dilute magnetic semiconductor GaMnAs using the variational envelope wave function approach within the framework of six band mod…
Positional Disorder, Spin-Orbit Coupling and Frustration in GaMnAs
Gregory A. Fiete, Gergely Zarand, Boldizsar Janko +2
We study the magnetic properties of metallic GaMnAs. We calculate the effective RKKY interaction between Mn spins using several realistic models for the valence band structure of G…
Shiba multiplets due to Mn impurities in MgB_2
Catalin Pascu Moca, Gergely Zarand, Eugene Demler +1
We study the effect of magnetic Mn ions on the two-band superconductor MgB_2, and compute both the total and spin resolved scanning tunneling spectrum in the vicinity of the magnet…
Superconducting Vortex Logic Antidots
C. J. Olson Reichhardt, C. Reichhardt, B. Janko
We examine a building block for logic devices in which the positions of superconducting vortices in coupled elongated antidots provide the elementary logic states of 0 and 1. We sh…
Signatures of interband scattering in spectroscopic experiments on
C. P. Moca, B. Janko
Within a two-band, strong coupling model we analyze SIS-tunneling conductance, Raman scattering and optical conductivity measured on samples. We find that features observed…
