Nano-scale heat transport in a Coulomb-coupled metallic-island

Heat flow at the mesoscopic scale is a fundamentally important issue, particularly if it can be converted into energy by the thermoelectric effect. While the understanding of charge transport in the mesoscopic system has reached a great level of maturity, heat transport lags far behind. According to the celebrated Wiedemann-Franz (WF) law, charge conductance is proportional to thermal conductance. In the first part of this talk, I will present combined measurements of charge and heat transport in a coulomb-coupled metallic island, also known as a single-electron transistor. A comparison of the measured heat and charge conductance shows a violation of the celebrated WF law, due to strong electronic interactions [1, 2]. 
In the second part of this talk, I will present my vision for my future research path and plans for building new lab and research group.
