Theoretical study of the electron dynamics of a quantum wire coupled with the quantum dots

We theoretically study the time evolution of the electronic state on a quantum wire (QW) coupled with the quantum dot (QD). We find that the characteristic of the electron density on the QW sensitively depends on the energy levels of the QDs. We systematically discuss the mechanism of these characteristic modulations by the projection analysis, where the time evolutions of the electron wave functions are clarified in terms of the superposition of the eigenstates of the QW-QD coupled system.
