Spin ordering in magnetic quantum dots: From core-halo to Wigner molecules

R. Oszwałdowski, P. Stano, A. G. Petukhov +1

The interplay of confinement and Coulomb interactions in quantum dots can lead to strongly correlated phases differing qualitatively from the Fermi liquid behavior. We explore how…

Spin-orbit coupled particle in a spin bath

Peter Stano, Jaroslav Fabian, Igor Žutić

We consider a spin-orbit coupled particle confined in a quantum dot in a bath of impurity spins. We investigate the consequences of spin-orbit coupling on the interactions that the…

Transition from fractional to Majorana fermions in Rashba nanowires

Jelena Klinovaja, Peter Stano, Daniel Loss

We study hybrid superconducting-semiconducting nanowires in the presence of Rashba spin-orbit interaction as well as helical magnetic fields. We show that the interplay between the…

Theory of Spin Relaxation in Two-Electron Lateral Coupled Si/SiGe Quantum Dots

Martin Raith, Peter Stano, Jaroslav Fabian

Highly accurate numerical results of phonon-induced two-electron spin relaxation in silicon double quantum dots are presented. The relaxation, enabled by spin-orbit coupling and th…

Magnetic properties of carbon nanodisk and nanocone powders

Jozef Cernak, Geir Helgesen, Jozef Kovac +2

We have investigated the magnetic properties of carbon powders which consist of nanodisks, nanocones, and a small fraction of carbon-black particles. Magnetization measurements wer…
