Strong Differential Photoion Circular Dichroism in Strong-Field Ionization of Chiral Molecules

K. Fehre, S. Eckart, M. Kunitski +14

We investigate the differential ionization probability of chiral molecules in the strong field regime as a function of the helicity of the incident light. To this end, we analyze t…

Zeptosecond Birth Time Delay in Molecular Photoionization

Sven Grundmann, Daniel Trabert, Kilian Fehre +11

Photoionization is one of the fundamental light-matter interaction processes in which the absorption of a photon launches the escape of an electron. The time scale of the process p…

Electric Nondipole Effect in Strong-Field Ionization

A. Hartung, S. Brennecke, K. Lin +10

Strong-field ionization of atoms by circularly polarized femtosecond laser pulses produces a donut-shaped electron momentum distribution. Within the dipole approximation this distr…

Chiral photoelectron angular distributions from ionization of achiral atomic and molecular species

Andreas Pier, Kilian Fehre, Sven Grundmann +12

We show that the combination of two achiral components - atomic or molecular target plus a circularly polarized photon - can yield chirally structured photoelectron angular distrib…

Angular dependence of the Wigner time delay upon tunnel ionization of

Daniel Trabert, Simon Brennecke, Kilian Fehre +9

More than 100 years after its discovery and its explanation in the energy domain, the duration of the photoelectric effect is still heavily studied. The emission time of a photoele…

Sideband Modulation by Sub-Cycle Interference

S. Eckart, D. Trabert, K. Fehre +9

We experimentally and theoretically show that the electron energy spectra strongly depend on the relative helicity in highly intense, circularly polarized two-color laser fields wh…

Revealing the Two-Electron Cusp in the Ground States of He and H2 via Quasifree Double Photoionization

S. Grundmann, V. Serov, F. Trinter +15

We report on kinematically complete measurements and ab initio non-perturbative calculations of double ionization of He and H2 by a single 800 eV circularly polarized photon. We co…
