State-resolved differential cross sections for the rotationally inelastic scattering of the Ar+NO system have been derived from quasiclassical trajectories and quantum close-coupling calculations on a recent ab initio potential energy surface at the collision energy of a recent high resolution experiment (66 meV). Globally good agreement is obtained between the theoretical predictions and experimental results, although some of the experimental details are not reproduced in the classical calculation. The role of attractive and repulsive interactions in the observed dynamical features is examined.

Prethermalization phenomena in weakly interacting Hubbard systems after electric‐field pump pulses with a finite duration are studied. The Hubbard interaction U is taken into account up to second order, by applying the prethermalization paradigm for time‐dependent interaction protocols, and the electric field strength beyond linear order. A scaling behavior with pulse duration is observed for the absorbed energy as well as individual prethermalized momentum occupation numbers, which are attributed to the leading quadratic orders in interaction and electric field. It is shown that a pronounced nonthermal momentum distribution can be created with pump pulses of suitable resonance frequencies, and how to distinguish them from thermal states is discussed.
