Phase-Programmable Free Electron Quantum States in Synthetic Momentum Space
Alatz Alvarez-Ahedo, Miriam Lazo, Tian-Niu Xu +3
Light-electron interactions generate synthetic momentum-space dynamics that can be used to engineer free electron quantum states. Here we develop coherent control protocols in whic…
Quantum echo-enabled high harmonic generation using ultrafast electrons
Yangfan He, Chenhao Pan, Bin Zhang +1
Controlling and generating ultrafast free-electron wavepackets via laser is pivotal for photon-induced near-field electron microscopes (PINEM) and also for developing compact, cohe…
Programming Coherent and Quantum Light with a Free-Electron Wavepacket
Songyu Zhu, Yushan Zeng, Chenhao Pan +3
The pursuit of compact, programmable light sources with high coherence and spectral purity hinges on establishing a precise set of phase relationships in light-matter interactions.…
Ultrafast Stern-Gerlach and Anomalous Bragg Diffraction Regimes of Low-energy Free Electron Interaction with Light
Yongcheng Ding, Zirui Zhao, Bin Zhang +3
Recent advances in photon-induced near-field electron microscopy (PINEM) have significantly impacted allied disciplines such as laser-driven accelerators and free electron radiatio…
Indirect multiphoton scattering between light and bulk plasmons via ultrafast free electrons
Ruoyu Chen, Jun Li, Qiaofei Pan +6
Efficient coupling between light and bulk plasmons (BPs) remains a central challenge because of their inherent mode mismatch, limited penetration depth, and pronounced resonant ene…
Generating and Weaving Topological Event Wavepackets in Photonic Spacetime Crystals with Fully Energy-Momentum Gapped
Liang Zhang, Zirui Zhao, Qiaofei Pan +3
We propose a novel type of topological excitation topological event wavepackets (TEWs) emerging in photonic spacetime crystals (STCs) with spacetime modulated dielectric constants.…
