We measure transport at finite bias through a double quantum dot formed by top-gates in an InAs nanowire. Pauli spin-bockade is confirmed with several electrons in the dot. This is expected due to the small exchange interactions in InAs and the large singlet-triplet splitting, which can be measured

We theoretically examine a small current through double quantum dots with Pauli spin blockade, in which electrons cannot be transported without spin-flip or higher-order tunnel processes (cotunneling). Analytical expressions for the current are given in both cases of sequential tunneling and resonan

We analyze the charge and spin dynamics in a double quantum dot driven by crossed DC and AC magnetic fields. The AC field produces coherent electron spin rotations within each quantum dot. In a double quantum dot, these oscillations compete with coherent inter-dot tunneling, giving rise to a complic

In this chapter we discuss various types of spin interaction in quantum dots. This involves spins from electrons and holes, as well as nuclear spins. The interaction of electrons includes the dipolar interaction of their spins as well as the Coulomb exchange interaction, which is an effective spin-s
