| Abstract | We demonstrate that the magnetoconductance of small lateral quantum dots in the strongly-coupled regime (i.e. when the leads can support one or more propagating modes) shows a pronounced splitting of the conductance peaks and dips which persists over a wide range of magnetic fields (from zero field to the edge-state regime) and is virtually independent of the magnetic field strength. Our numerical analysis of the conductance based on the Hubbard Hamiltonian demonstrates that this is essentially a many-body/spin effect that can be traced to a splitting of degenerate levels in the corresponding closed dot. The above effect in open dots can be regarded as a counterpart of the Coulomb blockade effect in weakly coupled dots, with the difference, however, that the splitting of the peaks originates from the interaction between the electrons of opposite spin. © 2005 American Institute of Physics. |
