The quantum interference beat of APINEM is capable of improving the spectral resolution of postselective electron microscopy and the particle-wave duality transition between regimes reveals the history-dependent nature of quantum electron interaction with light.Abstract:
We reveal the classical and quantum regimes of free electron interaction with radiation, common to the general variety of radiation sources (e.g., a Smith-Purcell radiation), the dielectric laser accelerator, and photo-induced near-field electron microscopy (PINEM). Modeling the electron with initial conditions of a coherent quantum electron wave packet, its topology in phase space uniquely defines a universal distinction of three interaction regimes: point-particle-like acceleration, a quantum wave function (PINEM), and a newly reported regime of anomalous PINEM (APINEM). The quantum interference beat of APINEM is capable of improving the spectral resolution of postselective electron microscopy. The particle-wave duality transition between regimes reveals the history-dependent nature of quantum electron interaction with light.read more

TL;DR: This concept is based on a recent demonstration of the optical frequency modulation of the free-electron quantum electron wave function by an ultrafast laser beam, and it is asserted that pulses of such QEWs correlated in their modulation phase, interact resonantly with two-level systems, inducing resonant quantum transitions.

TL;DR: In this paper, the quantum statistics effects of photons on free-electron-light interactions are observed, revealing a transition from quantum walk to classical random walk on the freeelectron energy ladder, and the electron walker serves as the probe in non-destructive quantum detection, measuring the second order photon-correlation g (2)(0) and higher order g ( n )(0).
