论文摘要
我们研究了来自二维拓扑系统的能量和角动量的辐射，其反转对称性和时间逆转对称性。使用2D材料对波动电磁场的线性响应开发了远场辐射的一般理论。将理论应用于Haldane模型，我们验证热辐射是否仅在低温下符合普朗克定律，并且随着温度变高而偏离它。该系统可能会有角动量辐射，并且随着温度升高而表现出饱和。研究和优化对辐射至关重要的参数。这项研究启发了将量子信息转换为角动量自由度的可能性。
We investigate the radiation of energy and angular momentum from 2D topological systems with broken inversion symmetry and time reversal symmetry. A general theory of far-field radiation is developed using the linear response of 2D materials to the fluctuational electromagnetic field. Applying the theory to the Haldane model, we verify that the heat radiation complies with Planck's law only at low temperature and deviates from it as temperature becomes high. Angular momentum radiation is possible for this system and exhibits saturation as temperature increases. Parameters crucial to the radiation are investigated and optimized. This research enlightens the possibility of transposing the quantum information to the angular momentum degree of freedom.
