Nondipole Contributions to Attosecond Chiral Photoionization Asymmetries
Zheming Zhou, Yang Li, Yueming Zhou +1
Photoelectron circular dichroism (PECD) reads molecular chirality from forward-backward asymmetries in photoelectron emission, but the same observable can also contain non-dipole c…
Vortex photoelectron holography in strong-field tunneling ionization
Yongkun Chen, Oleg I. Tolstikhin, Toru Morishita +2
Vortex electrons, characterized by a helical phase front, offer unique advantages for probing material structures. Such electrons can be generated via tunneling ionization in stron…
Anomalous Autler-Townes Splitting in Resonant Multiphoton Ionization Driven by Bright Squeezed Vacuum
Xu Zhang, Liding Li, Yutong Deng +5
Bright squeezed vacuum (BSV) light has a vanishing mean optical electric field yet can strongly enhance strong-field nonlinear responses beyond the conventional semiclassical parad…
Attosecond-Resolved Photoionization Dynamics and Interference-Enhanced Photoelectron Circular Dichroism in Chiral Molecules
Zheming Zhou, Yang Li, Xu Zhang +2
Chiral molecules exhibit enantiosensitive light-matter interactions, with photoelectron circular dichroism (PECD) serving as a sensitive probe of molecular chirality through the as…
