Electron Transport through Driven Mesoscopic Systems

The study of electron properties of submicron and nanoscale devices is a growing field, promising not only unprecedented advances in conventional electronics, but also breakthroughs in quantum information. I will discuss the current-voltage characteristics of these devices in the presence of high frequency electro-magnetic fields and review recent theoretical and experimental results. First, I will consider charge pumping generated by classical electro-magnetic fields in the absence of voltage across the dot. I will also describe the effect of electro-magnetic fields on the quantum
interference corrections to the conductance. Then, I will analyze the effect of quantized electro-magnetic fields on the current-voltage characteristics of mesoscopic devices.I will show that these devices can be used as detectors to determine temperature and other characteristics of electro-magnetic fields.
