Few-electron open dots: Single level transport

We confirm the existence of anew regime for small few-electron open dots, i n which the transport occurs through individual eigenstates of the correspo nding closed dot. In particular, at low magnetic fields the characteristic features in the conductance are related to the underlying eigenspectrum she lls. When the number of modes in the leads is reduced, a more detailed stru cture becomes discernible within the shells due to single eigenlevels. At h igher fields Landau level condensation is evident as well as the crossing o f levels collapsing to different Landau levels.
