中文摘要	we have studied the equilibrium and nonequilibrium electronic transports through a double quantum dot coupled to leads in a symmetrical parallel configuration in the presence of both the inter- and the intradot coulomb interactions. the influences of the interdot interaction and the difference between dot levels on the local density of states (ldos) and the differential conductance are paid special attention. we find an interesting zero-bias maximum of the differential conductance induced by the interdot interaction, which can be interpreted in terms of the ldos of the two dots. due to the presence of the interdot interaction, the ldos peaks around the dot levels epsilon(i) are split, and as a result, the most active energy level which supports the transport is shifted near to the fermi level of the leads in the equilibrium situation.
