Electrically-tunable hole g-factor of an optically-active quantum dot for fast spin rotations

Jonathan H. Prechtel, Franziska Maier, Julien Houel +5

We report a large g-factor tunability of a single hole spin in an InGaAs quantum dot via an electric field. The magnetic field lies in the in-plane direction x, the direction requi…

Majorana Fermions in Ge/Si Hole Nanowires

Franziska Maier, Jelena Klinovaja, Daniel Loss

We consider Ge/Si core/shell nanowires with hole states coupled to an -wave superconductor in the presence of electric and magnetic fields. We employ a microscopic model that ta…

Strongly Interacting Holes in Ge/Si Nanowires

Franziska Maier, Tobias Meng, Daniel Loss

We consider holes confined to Ge/Si core/shell nanowires subject to strong Rashba spin-orbit interaction and screened Coulomb interaction. Such wires can, for instance, serve as ho…

Nuclear Spin Diffusion Mediated by Heavy Hole Hyperfine Non-Collinear Interactions

Hugo Ribeiro, Franziska Maier, Daniel Loss

We show that the hyperfine mediated dynamics of heavy hole states confined in neutral self- assembled quantum dots leads to a nuclear spin diffusion mechanism. It is found that the…

Anisotropic g factor in InAs self-assembled quantum dots

Robert Zielke, Franziska Maier, Daniel Loss

We investigate the wave functions, spectrum, and g-factor anisotropy of low-energy electrons confined to self-assembled, pyramidal InAs quantum dots (QDs) subject to external magne…

Tunable g factor and phonon-mediated hole spin relaxation in Ge/Si nanowire quantum dots

Franziska Maier, Christoph Kloeffel, Daniel Loss

We theoretically consider g factor and spin lifetimes of holes in a longitudinal Ge/Si core/shell nanowire quantum dot that is exposed to external magnetic and electric fields. For…

Effect of strain on hyperfine-induced hole-spin decoherence in quantum dots

Franziska Maier, Daniel Loss

We theoretically consider the effect of strain on the spin dynamics of a single heavy-hole (HH) confined to a self-assembled quantum dot and interacting with the surrounding nuclei…
