Simple Summation

We study the transport properties of electrons in a quantum wire with side-coupled quantum dots in Coulomb blockade regime by the use of the equivalent single-particle multi-channel network and Landauer formula. At low temperatures the calculated dependence of the conductance on the gate voltage of dots exhibits two dips, indicating the destructive interference of the wave directly transmitted through the wire and the wave reflected from the dots. In a wire with more than one side-coupled dots the suppression of conductance is a simple summation of the effects of scattering of all the dots. The possibility of fabricating tunable switch devices by using such structures is discussed.

Numerical Techniques

We present a short review on electron transport in strongly correlated nanostructures, quantum dots in particular. We describe briefly the main correlation effects, namely the Coulomb blockade and Kondo effect, and introduce three widely used numerical techniques to study these effects. We then give a brief summary of some more elaborate set-ups where two or more effects compete, making the transport properties very interesting to study. In particular, we report the cases of multilevel quantum dots, carbon nanotube based quantum dots, and quantum dots coupled by RKKY interaction.
