A near-field thermal Hall effect (i.e., Righi-Leduc effect) in networks of magneto-optical particles placed in a constant magnetic field is predicted. This many-body effect is related to a symmetry breaking in the system induced by the magnetic field, which gives rise to preferential channels for the heat transport by near-field interaction thanks to the particle's anisotropy tuning.
预测了放置在恒磁场中的磁光粒子网络中的近场热霍尔效应(即里吉-勒迪克效应)。这种多体效应与磁场引起的系统对称性破缺有关,由于粒子的各向异性调谐,这导致了通过近场相互作用进行热输运的优先通道。
