On the role of shake-off in single-photon double ionization
T. Pattard, T. Schneider, J. M. Rost
The role of shake-off for double ionization of atoms by a single photon with finite energy has become the subject of debate. In this letter, we attempt to clarify the meaning of sh…
Ultrahigh harmonics from laser-assisted ion-atom collisions
Manfred Lein, Jan M. Rost
We present a theoretical analysis of high-order harmonic generation from ion-atom collisions in the presence of linearly polarized intense laser pulses. Photons with frequencies si…
Quasiclassical double photoionization from the 2^{1,3}S excited states of helium including shakeoff
A. Emmanouilidou, T. Schneider, J. -M. Rost
We account for the different symmetries of the 2^{1,3}S helium excited states in a quasiclassical description of the knockout mechanism augmented by a quantum shakeoff contribution…
Plasma formation from ultracold Rydberg gases
T. Pohl, T. Pattard, J. M. Rost
Recent experiments have demonstrated the spontaneous evolution of a gas of ultracold Rydberg atoms into an expanding ultracold plasma, as well as the reverse process of plasma reco…
