The beryllium atom and beryllium positive ion in strong magnetic fields
M. V. Ivanov, P. Schmelcher
The ground and a few excited states of the beryllium atom in external uniform magnetic fields are calculated by means of our 2D mesh Hartree-Fock method for field strengths ranging…
Quantum energy flow in atomic ions moving in magnetic fields
Vladimir Melezhik, Peter Schmelcher
Using a combination of semiclassical and recently developed wave packet propagation techniques we find the quantum self-ionization process of highly excited ions moving in magnetic…
Excited states of the hydrogen molecule in magnetic fields: The singlet Sigma states of the parallel configuration
Peter Schmelcher, Thomas Detmer, Lorenz Cederbaum
Excited states of the hydrogen molecule subject to a homogeneous magnetic field are investigated for the parallel configuration in the complete regime of field strengths B=0-100a.u…
Finite-Difference Calculations for Atoms and Diatomic Molecules in Strong Magnetic and Static Electric Fields
Mikhail V. Ivanov, Peter Schmelcher
Fully numerical mesh solutions of 2D quantum equations of Schroedinger and Hartree-Fock type allow us to work with wavefunctions which possess a very flexible geometry. This flexib…
Bound states of negatively charged ions induced by a magnetic field
Victor G. Bezchastnov, Peter Schmelcher, Lorenz S. Cederbaum
We analyse the bound states of negatively charged ions which were predicted to exist because of the presence of a magnetic field by Avron et al. We confirm that the number of such…
Analysing Lyapunov spectra of chaotic dynamical systems
Fotis Diakonos, Detlef Pingel, Peter Schmelcher
It is shown that the asymptotic spectra of finite-time Lyapunov exponents of a variety of fully chaotic dynamical systems can be understood in terms of a statistical analysis. Usin…
