Abstract
In this paper, heat current through a single-level quantum dot between two non-magnetic leads has been studied. The system is in non-equilibrium caused by different temperatures at leads. The Anderson model is used to model quantum dot with a single spin-degenerated level. The equations of the energy levels and their occupation of the quantum dot are solved self-consistently; then the heat current is calculated as a function of temperature difference with the effect of the magnetic field. According to my study, four parameters must be tuned to realize heat current rectification. These parameters are: the magnetic field, the Coulomb correlation, the coupling with the leads, and the lower level with the spin \(\sigma \) is blocked, while the upper one with spin \(\sigma \) must be opened.
