Mass-ratio dependent strong-field dissociation of artificial helium hydride isotopologues
Florian Oppermann, Saurabh Mhatre, Stefanie Gräfe +1
We study the effect of the nuclear-mass ratio in a diatomic molecular ion on the dissociation dynamics in strong infrared laser pulses. A molecular ion is a charged system, in whic…
The Rough with the Smooth of the Light Cone String
Norbert Dragon, Florian Oppermann
The polynomials in the generators of a unitary representation of the Poincaré group constitute an algebra which maps the dense subspace S of smooth, rapidly decreasing wavefunction…
Heisenberg versus the Covariant String
Norbert Dragon, Florian Oppermann
A Poincaré multiplet of mass eigenstates cannot be a subspace of a space with a -vector position operator : the Heisenberg alg…
Heisenberg Algebra and String Theory
Norbert Dragon, Florian Oppermann
If the algebra of the Poincaré generators is enlarged by the spacetime position operator then the spectra of the momentum and the mass are unboun…
Strong-Field Polarizability-Enhanced Dissociative Ionization
Lun Yue, Philipp Wustelt, A. Max Sayler +2
We investigate dissociative single and double ionization of HeH+ induced by intense femtosecond laser pulses. By employing a semi-classical model with nuclear trajectories moving o…
Heteronuclear Limit of Strong-Field Ionization: Fragmentation of HeH by Intense Ultrashort Laser Pulses
P. Wustelt, F. Oppermann, Lun Yue +6
The laser-induced fragmentation dynamics of this most fundamental polar molecule HeH are measured using an ion beam of helium hydride and an isotopologue at various wavelengths…
