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…

Vortex motion rectification in Josephson junction arrays with a ratchet potential
D. E. Shalom, H. Pastoriza
By means of electrical transport measurements we have studied the rectified motion of vortices in ratchet potentials engineered on over-damped Josephson junction arrays. The rectif…

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…
