Abstract Phenomena of free-electron X-ray radiation are treated almost exclusively with classical electrodynamics, despite the intrinsic interaction being that of quantum electrodynamics. The lack of quantumness arises from the vast disparity between

Abstract Bremsstrahlung—the spontaneous emission of broadband radiation from free electrons that are deflected by atomic nuclei—contributes to the majority of X-rays emitted from X-ray tubes and used in applications ranging from medical imaging t

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

The limits of topological protection in photonic systems remain unclear. Here, Gao et al. construct photonic topological edge states and probe their robustness against a variety of defect classes, including some common time-reversal-invariant photoni

Recently, a proposal of synthetic gauge field in reduced two-dimensional (2D) system from three-dimensional (3D) acoustic structure shows an analogue of the gapped Haldane model with fixed k _z , and achieves the gapless Weyl semimetal phase in 3D mo

Laser light can modulate the kinetic energy spectrum of free electrons and induce extremely high acceleration gradients, which are instrumental to electron microscopy and electron acceleration, respectively. We present a design scheme for a silicon p

Quantum light–matter interactions of bound electron systems have been studied extensively. By contrast, quantum interactions of free electrons with light have only become accessible in recent years, following the discovery of photon-induced near-fi

We present the concept of customized van der Waals heterostructures with periodicity tailored to generate pre-designed X-ray patterns from free electrons. As an example, we demonstrate focused X-ray beams.

Photons emitted via bremsstrahlung are inherently incoherent and non-directional. We show that the intrinsic cross-section of bremsstrahlung from crystalline solids can be enhanced and made directional by shaping the quantum wave nature of free elect

Tunable nanoscale shaping of X-ray waves remains as an open challenge of critical importance for applications in high-resolution X-ray spectroscopy and imaging. In contrast to this high photon energy regime, shaping of light waves in the visible and
