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…

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…
