Query: Attosecond VUV Coherent Control of Molecular Dynamics   High harmonic light sources make it possible to access attosecond
time-scales, thus opening up the prospect of manipulating electronic wave
packets for steering molecular dynamics. However, two decades after the birth
of attosecond physics, the concept of attosecond chemistry has not yet been
realized. This is because excitation and manipulation of molecular orbitals
requires precisely controlled attosecond waveforms in the deep ultraviolet,
which have not yet been synthesized. Here, we present a novel approach using
attosecond vacuum ultraviolet pulse-trains to coherently excite and control the
outcome of a simple chemical reaction in a deuterium molecule in a non-Born
Oppenheimer regime. By controlling the interfering pathways of electron wave
packets in the excited neutral and singly-ionized molecule, we unambiguously
show that we can switch the excited electronic state on attosecond timescales,
coherently guide the nuclear wave packets to dictate the way a neutral molecule
vibrates, and steer and manipulate the ionization and dissociation channels.
Furthermore, through advanced theory, we succeed in rigorously modeling
multi-scale electron and nuclear quantum control in a molecule for the first
time. The observed richness and complexity of the dynamics, even in this very
simplest of molecules, is both remarkable and daunting, and presents intriguing
new possibilities for bridging the gap between attosecond physics and
attochemistry.
