The emerging application of attosecond techniques to molecular systems allows the role of
electronic coherence in the control of chemical reactions to be investigated. Prompt …

The question of how long it takes a particle to tunnel through a potential barrier has been a
subject of intense theoretical debate for the last 80 years. In this decade of attosecond …

With the discovery of above-threshold ionization (ATI) by Agostini et al.(1979) intense-laser
atom physics entered the nonperturbative regime. These experiments recorded the …

The first hundred attoseconds of the electron dynamics during strong field tunneling
ionization are investigated. We quantify theoretically how the electron's classical trajectories …

We investigate experimentally the validity of proposed theories extending the tunneling
approximation towards the multiphoton regime in strong-field ionization of helium. We …

We investigate tunneling ionization of a single active electron with a strong and short laser
pulse, circularly polarized. With the recently proposed backpropagation method, we can …

The last decade has seen an intense renewed debate on tunnelling time, both from a
theoretical and an experimental perspective. Here, we review recent developments and new …

We present simple new approximate formulas, for both scalar and spinor QED, for the
number of particles produced from vacuum by a time-dependent electric field, incorporating …

We present an ellipticity-resolved study of momentum distributions arising from strong-field
ionization of helium. The influence of the ion potential on the departing electron is …

Laser-induced electron tunneling ionization from atoms and molecules plays as the trigger
for a broad class of interesting strong-field phenomena in attosecond community …
