Optical Coherence Transfer Mediated by Free Electrons (FM1L.1)
Presenter: Ofer Kfir, Max Planck Institute for Biophysical Chemistry

We investigate the optical coherence properties carried by the quantum state of a single free-flying charged and massive particle – the electron. We propose feasible Mach-Zehnder-like linear and nonlinear optical interferometric detection, incorporating electron-microscope beams.

Active Spatial Modulation of Free Electrons by Controlling the Shape and Intensity of Plasmonic Fields (FM1L.2)
Presenter: Shai Tsesses, Technion-Israeli institute of technology

We present active spatial shaping of free-electron wavepackets through their interaction with specially-designed interference patterns of surface plasmons and via the nonlinear intensity dependence of the electron-plasmon interaction.

Free-Electron Quantum Optics (FM1L.3)
Presenter: Ido Kaminer, Technion Israel Institute of Technology

Recent years created a paradigm-shift in our understanding of the fundamental interaction between free electrons and light. We use these developments for novel free-electron-polariton interactions in 2D materials, ultrastrong single-electron-single-photon interactions, and free-electron-light entanglement.

Quantum-to-Classical Transition of Laser-Shaped Ultrafast Free Electrons in Phase Space (FM1L.4)
Presenter: Bin Zhang, Tel Aviv University

Here, we propose a Smith-Purcell model for shaping free electrons with laser. We find that the quantum interference and deformation of the modulated electrons in phase space are vital for understanding the quantum-to-classical transition.

A General Framework for Shaping Luminescence in Materials (FM1L.5)
Presenter: Charles Roques-Carmes, MIT

We develop a general framework to describe non-equilibrium radiation by materials in nanophotonic structures (such as photoluminescence/cathodoluminescence/scintillation). We demonstrate the concept experimentally, enhancing and shaping cathodoluminescence from a silica photonic crystal.

Observation of 2D Cherenkov Radiation and its Quantized Photonic Nature Using Free-Electrons (FM1L.6)
Presenter: Yuval Adiv, Technion-Israeli institute of technology

Using a dispersion-engineered structure supporting hybrid photonic-plasmonic surface polaritons, we present the first observation of 2D Cherenkov radiation from free electrons, with record-strong electron–polariton quantum coupling that reaches the single-electron-single-photon interaction regime.

Enhanced Photon Emission of Metallic Cylindrical Ridges Upon Interaction With a Free Electron (FM1L.7)
Presenter: Ayan Nussupbekov, Nanyang Technological University

We show that free electron radiation from metal films can be enhanced by over two orders of magnitude with the introduction of a cylindrical nanoridge, compared to previously studied structures such as bullseye gratings.
