抄録

We theoretically study the spin Hall effect (SHE) in multi-terminal quantum-dot system with spin-orbit interaction. First, we analytically formulate the SHE around current peaks of the Coulomb oscillation. The SHE is remarkably enhanced by the resonant tunneling when the energy level spacing is smaller than the level broadening in the quantum dot. Next, we examine the many-body resonance by the Kondo effect in the Coulomb blockade regime. A large SHE is observed in the presence of SU(4) Kondo effect when the level spacing is smaller than the Kondo temperature.
