  Ultrafast optical techniques allow to study ultrafast molecular dynamics
involving both nuclear and electronic motion.To support interpretation,
theoretical approaches are needed that can describe both the nuclear and
electron dynamics.Hence, we revisit and expand our ansatz for the coupled
description of the nuclear and electron dynamics in molecular systems (NEMol).
In this purely quantum mechanical ansatz the quantum-dynamical description of
the nuclear motion is combined with the calculation of the electron dynamics in
the eigenfunction basis. The NEMol ansatz is applied to simulate the coupled
dynamics of the molecule NO2 in the vicinity of a conical intersection (CoIn)
with a special focus on the coherent electron dynamics induced by the
non-adiabatic coupling. Furthermore, we aim to control the dynamics of the
system when passing the CoIn. The control scheme relies on the carrier envelope
phase (CEP) of a few-cycle IR pulse. The laser pulse influences both the
movement of the nuclei and the electrons during the population transfer through
the CoIn.
