  • Attoclock with bicircular laser fields as a probe of velocity-dependent tunnel-exit positions 
    Brennecke, Simon; Eckart, Sebastian; Lein, Manfred (Bristol : IOP Publ., 2021)
    Strong-field ionization of atoms can be investigated on the attosecond time scale by using the attoclock method, i.e. by observing the peak of the photoelectron momentum distribution (PMD) after applying a laser pulse with ...
  • Dissociation and ionization of HeH+in sub-cycle-controlled intense two-color fields 
    Oppermann, F.; Wustelt, P.; Florin, T.; Mhatre, S.; Gräfe, S.; Paulus, G.G.; Lein, M. (Bristol : Institute of Physics Publishing, 2020)
    Using quantum-mechanical, one-dimensional, non-Born-Oppenheimer simulations we study the control over the strong-field dynamics of the helium hydride molecular ion HeH+ due to interaction driven by short and strong two-color ...
  • Electron Momentum Distributions from Strong-Field-Induced Ionization of Atoms and Molecules 
    Brennecke, Simon (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    High-intensity femtosecond laser pulses in the visible or infrared range can induce electron emission. This single-ionization process may be interpreted as a sequence of (nonadiabatic) tunnel ionization and subsequent ...
  • The HeH⁺ isotopologues in intense asymmetric laser fields 
    Oppermann, Florian (Hannover : Institutionelles Repositorium der Gottfried Wilhem Leibniz Universität Hannover, 2023)
    In this thesis, the effects of intense laser pulses on molecular dynamics are studied at the example of the helium hydride molecular ion HeH⁺. It serves as a benchmark system for asymmetric molecules because it has features ...
  • Mass-ratio dependent strong-field dissociation of artificial helium hydride isotopologues 
    Oppermann, F.; Mhatre, S.; Gräfe, S.; Lein, M. (Bristol : IOP Publ., 2023)
    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 which the dipole moment depends on the reference ...
  • Real-time propagator eigenstates 
    Oppermann, F.; Eicke, N.; Lein, M. (Bristol : IOP Publ., 2022)
    Obtaining a numerical solution of the time-dependent Schrödinger equation requires an initial state for the time evolution. If the system Hamiltonian can be split into a time-independent part and a time-dependent perturbation, ...
