Non-radiating angularly accelerating electron waves
Jordan Pierce, Jason Webster, Hugo Larocque +3
Accelerating electrons are known to radiate electromagnetic waves, a property that is central to the concept of many devices, from antennas to synchrotrons. While the electrodynami…
Interaction-Free Ghost-Imaging of Structured Objects
Yingwen Zhang, Alicia Sit, Frédéric Bouchard +6
Quantum - or classically correlated - light can be employed in various ways to improve resolution and measurement sensitivity. In an "interaction-free" measurement, a single photon…
Towards a holographic approach to spherical aberration correction in scanning transmission electron microscopy
Vincenzo Grillo, Amir H. Tavabi, Emrah Yucelen +11
Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this conce…
Nondestructive Measurement of Orbital Angular Momentum for an Electron Beam
Hugo Larocque, Frédéric Bouchard, Vincenzo Grillo +6
Free electrons with a helical phase front, referred to as "twisted" electrons, possess an orbital angular momentum (OAM) and, hence, a quantized magnetic dipole moment along their…
