Comparison of different approaches to the longitudinal momentum spread after tunnel ionization
Cornelia Hofmann, Alexandra S. Landsman, Claudio Cirelli +2
We introduce a method to investigate the longitudinal momentum spread resulting from strong-field tunnel ionization of Helium which, unlike other methods, is valid for all elliptic…

Tunneling Time in Ultrafast Science is Real and Probabilistic
Alexandra Landsman, Matthias Weger, Jochen Maurer +6
We compare the main competing theories of tunneling time against experimental measurements using the attoclock in strong laser field ionization of helium atoms. Refined attoclock m…

Probing the longitudinal momentum spread of the electron wave packet at the tunnel exit
Adrian N. Pfeiffer, Claudio Cirelli, Alexandra S. Landsman +4
We present an ellipticity resolved study of momentum distributions arising from strong-field ionization of Helium at constant intensity. The influence of the ion potential on the d…
