| Abstract: | Variations of the Coulomb oscillations with the in-plane magnetic field (the spin splitting) are theoretically studied to find many-body effects in tunneling through a quantum dot. The conductance and the transmission coefficient are calculated at small tunneling rates in the absence of spin-orbit interactions and expressed in terms of universal functions of the spin splitting, which have no dependence on details of wave functions except the magnitude of spin. Such universal functions are shown to be useful in observing the correlation between tunnelings of electrons with opposite spins and the dephasing due to spin flips. |
