Abstract
We study electron transport through laterally coupled double quantum dots. We introduce the coupling parameter α, which characterizes the strength of the coupling via the reservoirs between quantum dots. We find that the visibility decreases as |α| increases. We also examine the pseudo-spin Kondo effect in the laterally coupled double quantum dots. The differential conductance shows the additional structure in the spilt peak by the inter-dot tunnel coupling due to the asymmetry of the spectral density of states.
