Statistics of charge and heat in quantum dot thermal engines

Rafael Sanchez, ICMM-CSIC, Spain

Capacitively coupled conductors permit separate directions of the heat and current flux. Energy is transferred between two conductors by means of electron-electron interaction. When one of systems is at a higher temperature, the transferred heat can be converted to electrical power. In quantum dot systems, the energy transfer is discrete, allowing for high conversion efficiencies [1]. Charge fluctuations of such a system can be monitored by quantum point contact. Thus the transferred heat statistics can be extracted from the detection of state-resolved charge fluctuations [2]. I will discuss that this information is relevant in the context of non equilibrium charge fluctuation theorems and what we learn about the charge and heat auto- and cross-correlations [3]. [1] R. S
