Reconstructing Molecular-Ion Quantum States with Two-Color Strong-Field Scattering
Dina S. Eissa, Felipe Morales, Abraham Camacho Garibay +6
Strong-field ionization of molecules can prepare coherent superpositions of ionic states whose amplitudes and relative phases govern the ensuing ultrafast dynamics, but accessing t…
Evidence of ac-Stark-shifted resonances in intense two-color circularly polarized laser fields
Philipp Stammer, Serguei Patchkovskii, Felipe Morales
We report on the appearance of a structure at low energies in the photo-electron momentum distribution of the hydrogen atom exposed to two-color counter-rotating bi-circular laser…
Imprinting chirality on atoms using synthetic chiral light fields
Nicola Mayer, Serguei Patchkovskii, Felipe Morales +2
Atoms are usually thought of as achiral objects. However, one can construct superpositions of atomic states that are chiral [1]. Here we show how to excite such superpositions with…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
Electron spin polarization in strong-field ionization of Xenon atoms
Alexander Hartung, Felipe Morales, Maksim Kunitski +10
As a fundamental property of the electron, the spin plays a decisive role in the electronic structure of matter from solids to molecules and atoms, e.g. causing magnetism. Yet, des…
Attosecond control of spin polarization in electron-ion recollision driven by intense tailored fields
David Ayuso, Álvaro Jiménez-Galán, Felipe Morales +2
We show that electrons recolliding with the ionic core upon tunnel ionization of noble gas atoms driven by a strong circularly polarized laser field in combination with a counter-r…
Two-particle interference of electron pairs on a molecular level
M. Waitz, D. Metz, J. Lower +19
We investigate the photo-doubleionization of molecules with 400 eV photons. We find that the emitted electrons do not show any sign of two-center interference fringes in thei…
Opportunities for detecting ring currents using the attoclock set-up
Jivesh Kaushal, Felipe Morales, Olga Smirnova
Strong field ionization by circularly polarized laser fields from initial states with internal orbital momentum has interesting propensity rule: electrons counter-rotating with res…
Interpreting Attoclock Measurements of Tunnelling Times
Lisa Torlina, Felipe Morales, Jivesh Kaushal +8
Resolving in time the dynamics of light absorption by atoms and molecules, and the electronic rearrangement this induces, is among the most challenging goals of attosecond spectros…
