Spin-orbit signatures in the dynamics of singlet-triplet qubits in double quantum dots
Juan E. Rolon, Ernesto Cota, Sergio E. Ulloa
We characterize numerically and analytically the signatures of the spin-orbit interaction in a two-electron GaAs double quantum dot in the presence of an external magnetic field. I…
Quasienergy spectrum and tunneling current in ac-driven triple quantum dot shuttles
J Villavicencio, I Maldonado, E Cota +2
The dynamics of electrons in ac driven double quantum dots have been extensively analyzed by means of Floquet theory. In these systems, coherent destruction of tunneling has been s…
Removing spin blockade by photon-assisted tunneling in double quantum dots
R. Sánchez, G. Platero, R. Aguado +1
Pauli exclusion principle can lead to a supression of transport through double quantum dots, even if both quantum dots are connected by a resonant driving ac field. In this work, w…
Spin filtering through excited states in double quantum dot pumps
Rafael Sánchez, Ernesto Cota, Ramón Aguado +1
Recently it has been shown that ac-driven double quantum dots can act as spin pumps and spin filters. By calculating the current through the system for each spin polarization, by m…
Bipolar spin filter in a quantum dot molecule
F. Mireles, E. Cota, F. Rojas +1
We show that the tunable hybridization between two lateral quantum dots connected to non-magnetic current leads in a `hanging-dot' configuration that can be used to implement a bip…
AC-driven double quantum dots as spin pumps and spin filters
Ernesto Cota, Ramon Aguado, Gloria Platero
We propose and analyze a new scheme of realizing both spin filtering and spin pumping by using ac-driven double quantum dots in the Coulomb blockade regime. By calculating the curr…
