Title:Dynamic quantum transport in mesoscopic conductors
Abstract:
Dynamic quantum transport explores how time-dependent fields govern the flow of charge and heat at the nanoscale, where quantum coherence plays a central role. In my talk, I will introduce the field of dynamic quantum transport and present two of our recent works on negative interference currents and high-frequency heat pulses. First, I will show how interfering scattering paths through an electronic Fabry–Pérot cavity can make the electric current turn negative, even though the applied voltage pulses are always positive [1]. I will then go on to discuss how heat pulses can be emitted into a mesoscopic conductor by performing work on an electrode to change its temperature. We then investigate the properties of the heat pulses, for instance, by using a Hong-Ou-Mandel interferometer to examine if the heat pulses bunch or antibunch as they collide at an electronic beam splitter.
