Quantum dynamical properties of electron transfers through multiple quantum dots (QDs) are numerically investigated. The QDs are modeled as two-dimensional electron systems and the conductive properties are calculated from the time evolution of th...

By using quantum dynamics, we investigate an electron transport in a two-dimensional (2D) quantum structure under applied external fields. The structure is defined as a double tunnel junction which consists of ferromagnetic regions and insulator r...

We numerically investigate electron transfers in nanowires which consist of deoxyribonucleic acid (DNA) molecules (up to five base pairs for double-strands and seven bases for single-strands) by quantum dynamical calculations. DNA molecules are ap...
