Observation of the Stimulated Quantum Cherenkov Effect
Saar Nehemia, Raphael Dahan, Michael Shentcis +8
As charged particles surpass the speed of light in an optical medium they produce radiation - analogously to the way jet planes surpass the speed of sound and produce a sonic boom.…
Monochromatic X-ray source based on scattering from a magnetic nanoundulator
Sophie Fisher, Charles Roques-Carmes, Nicholas Rivera +3
We present a novel design for an ultra-compact, passive light source capable of generating ultraviolet and X-ray radiation, based on the interaction of free electrons with the magn…
Demonstration of weak measurements, projective measurements, and quantum-to-classical transitions in ultrafast free electron-photon interactions
Yiming Pan, Eliahu Cohen, Ebrahim Karimi +8
How does the quantum-to-classical transition of measurement occur? This question is vital for both foundations and applications of quantum mechanics. Here, we develop a new measure…
Quantum Emergence of Linear Particle Accelerator and Anomalous Photon-induced Near-field Electron Microscopy in a Strong Coupling Regime
Jing Zhou, Ido Kaminer, Yiming Pan
Photon-induced near-field electron microscopy (PINEM) is a currently developing spectral approach that characterizes quantum electron-light interactions in electron energy gain/los…
Coherent interaction between free electrons and a photonic cavity
Kangpeng Wang, Raphael Dahan, Michael Shentcis +5
Since its inception, research of cavity quantum electrodynamics (CQED) has extended our understanding of light-matter interactions and our ability to utilize them. Thus far, all th…
Free-Electron Qubits
Ori Reinhardt, Chen Mechel, Morgan Lynch +1
Free-electron interactions with laser-driven nanophotonic nearfields can quantize the electrons' energy spectrum and provide control over this quantized degree of freedom. We propo…
The Ramanujan Machine: Automatically Generated Conjectures on Fundamental Constants
Gal Raayoni, Shahar Gottlieb, George Pisha +6
Fundamental mathematical constants like and are ubiquitous in diverse fields of science, from abstract mathematics to physics, biology and chemistry. For centuries, new for…
Abruptly Focusing and Defocusing Needles of Light and Closed-Form Electromagnetic Wavepackets
Liang Jie Wong, Ido Kaminer
Fourier optics enforces a tradeoff between length and narrowness in electromagnetic wavepackets, so that a narrow spatial focus diffracts at a large divergence angle, and only infi…
Ultrashort Tilted-Pulse-Front Pulses and Nonparaxial Tilted-Phase-Front Beams
Liang Jie Wong, Ido Kaminer
Electromagnetic pulses with tilted pulse fronts are instrumental in enhancing the efficiency of many light-matter interaction processes, with prominent examples including terahertz…
Experimental Observation of Acceleration-Induced Thermality
Morgan H. Lynch, Eliahu Cohen, Yaron Hadad +1
We examine the radiation emitted by high energy positrons channeled into silicon crystal samples. The positrons are modeled as semiclassical vector currents coupled to an Unruh-DeW…
Maximal Spontaneous Photon Emission and Energy Loss from Free Electrons
Yi Yang, Aviram Massuda, Charles Roques-Carmes +7
Free electron radiation such as Cerenkov, Smith--Purcell, and transition radiation can be greatly affected by structured optical environments, as has been demonstrated in a variety…
Accelerated-Cherenkov radiation and signatures of radiation reaction
Morgan H. Lynch, Eliahu Cohen, Yaron Hadad +1
In this manuscript we examine an accelerated charged particle moving through an optical medium, and explore the emission of accelerated-Cherenkov radiation. The particle's reaction…
