Attosecond Control and Measurement of Chiral Photoionisation Dynamics
Meng Han, Jia-Bao Ji, Alexander Blech +5
Many chirality-sensitive light-matter interactions are governed by chiral electron dynamics. Therefore, the development of advanced technologies harnessing chiral phenomena would c…
Single photon zeptosecond interferometry
Geoffrey R. Harrison, Tobias Saule, R. Esteban Goetz +6
We demonstrate the generation of a train of attosecond XUV pulses that are in a superposition of wavefront states. Such superposition yields a high precision, self-referencing, com…
Continuum-electron interferometry for enhancement of photoelectron circular dichroism and measurement of bound, free, and mixed contributions to chiral response
R. Esteban Goetz, Alexander Blech, Corbin Allison +2
We develop photoelectron interferometry based on laser-assisted extreme ultraviolet ionization for flexible and robust control of photoelectron circular dichroism in randomly orien…
Quantum control of entangled photon-pair generation in electron-atom collisions driven by laser-synthesized free-electron wave packets
R. Esteban Goetz, Klaus Bartschat
We propose an extension of coherent control using laser-synthesized free-electron matter waves. In contrast to coherent control schemes exploiting optical coherences to steer the d…
Perfect control of photoelectron anisotropy for randomly oriented ensembles of molecules by XUV REMPI and polarization shaping
R. Esteban Goetz, Christiane P. Koch, Loren Greenman
We report two schemes to generate perfect anisotropy in the photoelectron angular distribution of a randomly oriented ensemble of polyatomic molecules. In order to exert full contr…
Quantum control of photoelectron circular dichroism
R. Esteban Goetz, Christiane P. Koch, Loren Greenman
We demonstrate coherent control over the photoelectron circular dichroism in randomly oriented chiral molecules, based on quantum interference between multiple photoionization path…
An adaptive-size multi-domain pseudospectral approach for solving the time-dependent Schrödinger equation
R. Esteban Goetz, Andrea Simoni, Christiane P. Koch
We show that a pseudospectral representation of the wavefunction using multiple spatial domains of variable size yields a highly accurate, yet efficient method to solve the time-de…
Theoretical description of circular dichroism in photoelectron angular distributions of randomly oriented chiral molecules after multi-photon photoionization
R. E. Goetz, T. A. Isaev, B. Nikoobakht +2
Photoelectron circular dichroism refers to the forward/backward asymmetry in the photoelectron angular distribution with respect to the propagation axis of circularly polarized lig…
Maximizing Hole Coherence in Ultrafast Photoionization of Argon with SPA-Optimization
R. Esteban Goetz, Maximilian Merkel, Antonia Karamatskou +2
Photoionization with attosecond pulses populates hole states in the photoion. Superpositions of hole states represent ideal candidates for time-dependent spectroscopy, for example…
Quantum optimal control of photoelectron spectra and angular distributions
R. Esteban Goetz, Antonia Karamatskou, Robin Santra +1
Photoelectron spectra and photoelectron angular distributions obtained in photoionization reveal important information on e.g. charge transfer or hole coherence in the parent ion.…
