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.

在本文中，研究了通过两个非磁性引线之间的单能级量子点的热电流。由于引线处的温度不同，系统处于非平衡状态。Anderson 模型用于模拟具有单个自旋简并能级的量子点。能级方程及其占据量子点的方程自洽求解；然后计算热流作为温度差和磁场影响的函数。根据我的研究，必须调整四个参数才能实现热电流整流。这些参数是：磁场、库仑相关性、与引线的耦合、低能级与自旋\(\sigma \)被阻挡，而高能级与自旋\(\sigma \) 必须打开。
