Tracking molecular hydrogen formation from ionized water in real time
Chuan Cheng, Chi-Hong Yuen, Eleanor Weckwerth +8
Removing an electron from a water molecule can drive its two hydrogen atoms to pair up and depart as molecular hydrogen. However, even for this elementary reaction, the route from…
Coherent Control of Three-Level System Using Shaped Free Electrons
Dixuan Wu, Jing Li, Yuhan Jiang +1
Three-level systems exhibit quantum interference effects absent in two-level systems, making them important for quantum optics. Here, we study the coherent interaction of a Lambda-…
Nanoscale Femtosecond Coherent Radiation and Spatiotemporally Shaped free electron Wavefunction
Wu Wen, Jing Li, Yunquan Liu
We study tunable nanoscale femtosecond coherent radiation based on a coupled nanowire pair (CNP) structure that is excited by a strong laser. The structure functions as a nanoscale…
Formation and Controlling of Optical Hopfions in High Harmonic Generation
Zijian Lyu, Yiqi Fang, Yunquan Liu
Toroidal vortex is a kind of novel and exotic structured light with potential applications in photonic topology and quantum information. Here, we present the study on high harmonic…
