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…
Magnetic Moment Formation in Quantum Point Contacts
P. S. Cornaglia, C. A. Balseiro, M. Avignon
We study the formation of local magnetic moments in quantum point contacts. Using a Hubbard-like model to describe point contacts formed in a two dimensional system, we calculate t…
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…
Transverse Electron Focusing in Systems with Spin-Orbit Coupling
Gonzalo Usaj, C. A. Balseiro
We study the transverse electron focusing in a two dimensional electron gas with Rashba spin-orbit coupling. We show that the interplay between the external magnetic field and the…
