Abstract Polaritons are well-established carriers of light, electrical signals, and even heat at the nanoscale in the setting of on-chip devices. However, the goal of achieving practical polaritonic manipulation over small distances deeply below the

Abstract The transformation of electromagnetic energy into matter represents a fascinating prediction of relativistic quantum electrodynamics that is paradigmatically exemplified by the creation of electron-positron pairs out of light. However, this

Abstract In electron microscopy, detailed insights into nanoscale optical properties of materials are gained by spontaneous inelastic scattering leading to electron-energy loss and cathodoluminescence. Stimulated scattering in the presence of externa

Abstract The science and technology of X-ray optics have come far, enabling the focusing of X-rays for applications in high-resolution X-ray spectroscopy, imaging, and irradiation. In spite of this, many forms of tailoring waves that had substantial

Existing approaches to modulating the properties of 2D materials typically involve heterostructuring or exposure to external fields. Here, the authors propose a gate-free non-contact approach to tuning the properties of a 2D semiconductor via the ima

Violating Kirchhoff's law is generally achieved using patterned nonreciprocal materials, where a guided or polaritonic mode that lies outside the light cone, often via gratings, is excited. Here, we describe how nonreciprocity manifests itself in pat
