Probing mesoscopic nonlocal screening in van der Waals heterostructures with polaritons
Xuezhi Ma, Zhipeng Li, Ruihuan Duan +17
Predictive optical modelling of van der Waals (vdW) heterostructures is critical for meta-optics, near-field photonics and quantum technologies. At their buried interfaces, charge…

Spatiotemporal Superfocusing
Qianru Yang, Haotian Wu, Hao Hu +3
Superfocusing confines light within subwavelength structures, breaking the diffraction limit. Structures with spatial singularities, such as metallic cones, are crucial to enable n…
