概要

• We propose a novel device where energy loss accompanied by current flow through a resistor is recovered, and therefore Joule heat production is exclusively low. This "energy-recovery effect" is caused by dynamical transition due to electronic coherent interference, namely Coulomb interaction within specially designed coupled quantum dots. We study the characteristics of this device as a resistor. We find a sudden drop of energy dissipation due to current flow as a function of electrochemical potential of the reservoir which is coupled to the quantum dots. In addition, we show that resistance of the device depends on the strength of the Coulomb interaction.
