Ultrafast electron vortex produced by a grating made of light
Zichen Li, Hao Liang, Yuan Gu +9
The generation of vortex matter waves carrying quantized orbital angular momentum is challenging and relies heavily on the material nanofabrication methods due to their extremely s…
Dynamical phase evolution of Coulomb-focused electrons in strong-field ionization probed by a standing light wave
Yuan Gu, Hao Liang, Weiran Zheng +13
We investigate the dynamical phase evolution of Coulomb-focused electrons in strong-field ionization. We diffract the electrons with an ultrashort standing light wave to track thei…
Chiral Electron Momentum Distribution upon Strong-Field Ionization of Atoms
A. Geyer, J. Stindl, I. Dwojak +14
We present a scheme to synthesize a three-dimensional laser field that produces a chiral electron momentum distribution upon strong-field ionization of atoms. Our approach employs…
Probing Instantaneous Single-Molecule Chirality in the Planar Ground State of Formic Acid
D. Tsitsonis, M. Kircher, N. M. Novikovskiy +12
We experimentally demonstrate that individual molecules of formic acid are chiral even when they are in the vibronic ground state, which has a planar equilibrium structure. We ioni…
