Data from the figures in the article "Coupling-energy driven pumping through quantum dots: the role of coherences"
Abstract
With this dataset, we publish all raw data from the calculations used and presented in arXiv:2602.23099 [cond-mat.mes-hall] (https://doi.org/10.48550/arXiv.2602.23099) or Phys. Rev. B 113, 235152 (2026) (https://doi.org/10.1103/m2jb-z9lm). This paper discusses electron pumping through a quantum dot theoretically. Thereby, the focus is on two pumping schemes where lowest-order and off-resonant tunneling processes are suppressed and the pump is exclusively driven by modulations of the coupling energy induced by coupling/decoupling processes or measurements. This dataset contains the calculated data of the currents through the quantum dot, the energetic efficiency of the pump, the quantum-dot occupation, the energies of the QD and the baths, and the QD-bath coherences. All calculations are done with Wolfram Mathematica 14, using an exact solution via the Heisenberg equation of motion technique, or by solving the Redfield equation.
