Fundamental quantum electrodynamical (QED) processes, such as spontaneous emission and electron-photon scattering, encompass phenomena that underlie much of modern science and technology. Conventionally, calculations in QED and other field theories treat incoming particles as single-momentum states, omitting the possibility that coherent superposition states, i.e., shaped wavepackets, can alter fundamental scattering processes. Here, we show that free electron waveshaping can be used to design… 
Comment on “Nonlinear quantum effects in electromagnetic radiation of a vortex electron”
This comment on the paper by Karlovets and Pupasov-Maksimov [Phys. Rev. A 103, 012214 (2021)] addresses their criticism of the combined experimental and theoretical study by Remez et al. [Phys. Rev.
Enhanced Versatility of Table-Top X-Rays from Van der Waals Structures.
Van der Waals (vdW) materials have attracted much interest for their myriad unique electronic, mechanical, and thermal properties. In particular, they are promising candidates for monochromatic,
Passage of a vortex electron over an inclined grating
We study Smith-Purcell radiation from a conducting grating generated by an inclined passage of a shaped electron wave packet with an electric quadrupole moment in the non-paraxial regime. Spreading
Promises and challenges of high-energy vortex states collisions
Vortex states of photons, electrons, and other particles are non–plane-wave solutions of the corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic orbital angular

Prospects in x-ray science emerging from quantum optics and nanomaterials
The science of x-rays is by now over 125 years old, starting with Wilhelm R€ontgen’s discovery of x-rays in 1895, for which R€ontgen was awarded the first Nobel Prize in Physics. X-rays have
Space‐Time Wave Packets from Smith‐Purcell Radiation
The result of this work indicates a viable way of generating space‐time wave packets at exotic frequencies such as the terahertz and X‐ray regimes, potentially paving the way toward new methods of shaping electromagnetic wave packets through free‐electron radiation.
Superradiance and Subradiance due to Quantum Interference of Entangled Free Electrons.
This Letter shows how a pair of coincident path-entangled electrons can demonstrate either super- or subradiant light emission, depending on the two-particle wave function, and suggests that light emission can be sensitive to the explicit quantum state of the emitting matter wave and possibly serve as a nondestructive measurement scheme for measuring the quantumState of many-body systems.
Beyond Fermi’s golden rule in free-electron quantum electrodynamics: acceleration/radiation correspondence
In this article, we present a unified reciprocal quantum electrodynamics (QED) formulation of free-electron and quantum–light interaction. For electron–light interactions, we bridge the underlying


Observing the Quantum Wave Nature of Free Electrons through Spontaneous Emission.
The measurements can be explained by the probability distribution approach wherein the electron interacts with the grating as a classical point charge, clarifying the transition between the classical and quantum regimes and shed light on the mechanisms that take part in general light-matter interactions.

Here we present a semiclassical analysis of spontaneous and stimulated radiative emission from unmodulated and optically-modulated electron quantum wavepackets. We show that the radiative
Inelastic ponderomotive scattering of electrons at a high-intensity optical travelling wave in vacuum
Electrons are diffracted by a standing light wave of light, a phenomenon known as the Kapitza–Dirac effect. A generalization of this effect opens perspectives for the manipulation of ultrashort

Slow swift electrons with low self-inertia interact differently with matter and light in comparison with their relativistic counterparts: they are easily recoiled, reflected, and also diffracted form
Generation of electron Airy beams
A non-spreading electron wavefunction that self-heals, restoring its original shape after passing an obstacle is observed, which opens up new avenues for steering electronic wave packets like their photonic counterparts, because the wave packets can be imprinted with arbitrary shapes or trajectories.
