Manipulating the torsion of molecules by strong laser pulses
C. B. Madsen, L. B. Madsen, S. S. Viftrup +6
A proof-of-principle experiment is reported, where torsional motion of a molecule, consisting of a pair of phenyl rings, is induced by strong laser pulses. A nanosecond laser pulse…
Probing isotope effects in chemical reactions using single ions
Peter F. Staanum, Klaus Hoejbjerre, Roland Wester +1
Isotope effects in reactions between Mg+ in the 3p 2P3/2 excited state and molecular hydrogen at thermal energies are studied through single reaction events. From only ~250 reactio…
Theoretical studies of high-harmonic generation: Effects of symmetry, degeneracy and orientation
C. B. Madsen, L. B. Madsen
Using a quantum mechanical three-step model we present numerical calculations on the high-harmonic generation from four polyatomic molecules. Ethylene (CH) serves as an exa…
Molecular orbitals and strong-field approximation
Thomas Kim Kjeldsen, Lars Bojer Madsen
V.I. Usachenko and S.-I. Chu [Phys. Rev. A {\bf 71}, 063410 (2005)] discuss the molecular strong-field approximation in the velocity gauge formulation and indicate that some of our…
Exact Nondipole Kramers-Henneberger Form of the Light-Atom Hamiltonian: An Application to Atomic Stabilization and Photoelectron Energy Spectra
M. Forre, S. Selsto, J. P. Hansen +1
The exact nondipole minimal-coupling Hamiltonian for an atom interacting with an explicitly time- and space-dependent laser field is transformed into the rest frame of a classical…
Strong Orientation Effects in Ionization of H by Short, Intense, High-Frequency Light Sources
S. Selsto, M. Forre, J. P. Hansen +1
We present three dimensional time-dependent calculations of ionization of arbitrarily spatially oriented H by attosecond, intense, high-frequency laser fields. The ionization…
