Magnetic breakdown of cyclotron orbits in systems with Rashba and Dresselhaus spin-orbit coupling
A. A. Reynoso, Gonzalo Usaj, C. A. Balseiro
We study the effect of the interplay between the Rashba and the Dresselhaus spin-orbit couplings on the transverse electron focusing in two-dimensional electron gases. Depending on…
Anomalous Josephson Current in Junctions with Spin-Polarizing Quantum Point Contacts
A. A. Reynoso, Gonzalo Usaj, C. A. Balseiro +2
We consider a ballistic Josephson junction with a quantum point contact in a two-dimensional electron gas with Rashba spin-orbit coupling. The point contact acts as a spin filter w…
Design and control of spin gates in two quantum dots arrays
Gonzalo Usaj, C. A. Balseiro
We study the spin-spin interaction between quantum dots coupled through a two dimensional electron gas with spin-orbit interaction. We show that the interplay between transverse el…
Theory of Edge States in Systems with Rashba Spin-Orbit Coupling
A. Reynoso, Gonzalo Usaj, M. J. Sanchez +1
We study the edge states in a two dimensional electron gas with a transverse magnetic field and Rashba spin-orbit coupling. In the bulk, the interplay between the external field pe…
Anisotropy in Ferromagnetic Nanoparticles: Level-to-Level Fluctuations of a Collective Effect
Gonzalo Usaj, Harold U. Baranger
We calculate the mesoscopic fluctuations of the magnetic anisotropy of ferromagnetic nanoparticles. A microscopic spin-orbit Hamiltonian considered as a perturbation of the much st…
Tuning the Non-local Spin-Spin Interaction between Quantum Dots with a Magnetic Field
Gonzalo Usaj, P. Lustemberg, C. A. Balseiro
We describe a device where the non-local spin-spin interaction between two quantum dots can be turned on and off and even changed sign with a very small magnetic field. The setup c…
