In this era of miniaturized devices, we have been trying to develop various quantum theories to describe charge transfer, transport, optical and magnetic phenomena within a unified approach. Towards this end, I shall discuss our efforts to understand Negative differential Resistance/Conductance (NDR/NDC) phenomena in molecules and quantum dots, using both voltage-constraint and current-constraint approaches [1-4]. I shall also discuss a few electronics work that we have carried out on DNA systems [5-7].
