✦ Synopsis

We review recent work on resonant Andreev tunneling through a strongly interacting quantum dot connected to a normal and to a superconducting lead. We derive a general expression for the current flowing in the structure and discuss the linear and nonlinear transport in the nonperturbative regime. New effects associated with the Kondo resonance combined with the two-particle tunneling arise. The Kondo anomaly in the I -V characteristics depends on the relative size of the gap energy and the Kondo temperature.

Recent measurements of mesoscopic tunneling and cotunneling fluctuations in Coulomb blockaded ballistic quantum dots are presented. The statistics and parametric fluctuations (as a function of magnetic field) of Coulomb blockade peak heights are found to be consistent with random-matrix-theory predi

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
