Dichroic Electron Emission Patterns from Oriented Helium Ions
Niclas Wieland, Klaus Bartschat, Filippa Dudda +17
We report a joint experimental and theoretical study using a combination of polarization-controlled free-electron-laser (FEL) and near-infra\-red (NIR) pulses in a synchronized two…
Circular Dichroism in Multiphoton Ionization of Resonantly Excited Helium Ions near Channel Closing
Rene Wagner, Markus Ilchen, Nicolas Douguet +16
The circular dichroism (CD) of photoelectrons generated by near-infrared (NIR) laser pulses using multiphoton ionization of excited He ions in the 3p(m=+1) state. The ions were…
Coherent control of multiphoton ionization of lithium atoms by a bichromatic laser field
Silva Mezinska, Alexander Dorn, Thomas Pfeifer +1
We demonstrate a left-right asymmetry control of the photo\-electron angular distribution in multi\-photon ionization of Li atoms by a bichromatic laser field. By delaying the fund…
Strong-Field Ionization Phenomena Revealed by Quantum Trajectories
Taylor Moon, Klaus Bartschat, Nicolas Douguet
We investigate the photoionization dynamics of atoms subjected to intense, ultrashort laser pulses through the use of quantum trajectories. This method provides a unique and consis…
Opportunities for Gas-Phase Science at Short-Wavelength Free-Electron Lasers with Undulator-Based Polarization Control
Markus Ilchen, Enrico Allaria, Primož Rebernik Ribič +44
Free-electron lasers (FELs) are the world's most brilliant light sources with rapidly evolving technological capabilities in terms of ultrabright and ultrashort pulses over a large…
Using circular dichroism to control energy transfer in multi-photon ionization
A. H. N. C. De Silva, D. Atri-Schuller, S. Dubey +9
Chirality causes symmetry breaks in a large variety of natural phenomena ranging from particle physics to biochemistry. We investigate one of the simplest conceivable chiral system…
Spin entanglement in elastic electron scattering from lithium atoms
K. Bartschat, S. Fonseca dos Santos
In two recent papers (Phys. Rev. Lett. {\bf 116} (2016) 033201; Phys. Rev. A {\bf 94} (2016) 032331), the possibility of continuously varying the degree of entanglement between an…
The interaction of excited atoms and few-cycle laser pulses
J. E. Calvert, Han Xu, A. J. Palmer +9
This work describes the first observations of the ionisation of neon in a metastable atomic state utilising a strong-field, few-cycle light pulse. We compare the observations to th…
Time-Dependent B-Spline R-Matrix Approach to Double Ionization of Atoms by XUV Laser Pulses
Xiaoxu Guan, O Zatsarinny, C J Noble +2
We present an {\it ab initio} and non-perturbative time-dependent approach to the problem of double ionization of a general atom driven by intense XUV laser pulses. After using a h…
