Thermodynamics of adiabatic pumping in quantum dots #
I will present a comprehensive study of adiabatic quantum pumping through a resonant level model, consisting of a single-level quantum dot connected to two fermionic leads. A self-contained thermodynamic framework for this model is developed using adiabatic expansion techniques, incorporating variations in the energy level of the dot and the tunneling rates with the thermal baths. This approach enables a detailed analysis of various examples of pumping cycles, with key thermodynamic quantities such as entropy production and dissipated power being computed. Important insights are revealed into the relationship between these thermodynamic quantities and the system's transport properties, including the pumped charge and charge noise. Notably, the entropy production rate approaches zero in the charge quantization limit, while the dissipated power obeys a quantization rule. These findings enhance the understanding of quantum pumping mechanisms and contribute to the broader field of quantum thermodynamics by linking transport phenomena with fundamental thermodynamic principles.
