Open AccessDipole instability in molecules irradiated by XUV pulses
We study the response of small covalent molecules to XUV laser pulses. The theoretical description relies on a real-time and real-space Time-Dependent Density Functional Theory (TDDFT) approach at the level of...

On the stability of hole states in molecules and clusters
Recent investigations of the electron dynamics of molecules after irradiation with a short, strong XUV pulse have shown that under certain conditions, a rather clean deep hole state can be generated which, in ...

Self-interaction-correction and electron removal energies
The paper addresses the problem of the self-interaction correction (SIC) in static calculations of atoms and molecules. Key observable is the electron removal energy, the energy required to remove one electron...

Emission and collisional correlation in far-off equilibrium quantum systems
We propose a scheme to describe dynamical correlations in finite fermion systems which are open in the sense that they can lose particles, electrons in the present case. It is built as an extension of recently...

Open AccessCharge radii of exotic potassium isotopes challenge nuclear theory and the magic character of N = 32
Nuclear charge radii are sensitive probes of different aspects of the nucleon–nucleon interaction and the bulk properties of nuclear matter, providing a stringent test and challenge for nuclear theory. Experim...

Open AccessProbing electron dynamics by IR+XUV pulses
By recording observables of electron emission we analyze the response of small metal clusters and organic molecules to a pump probe setup using an IR fs laser pulse as pump followed by an attosecond XUV pulse ...

Open AccessMeasurement and microscopic description of odd–even staggering of charge radii of exotic copper isotopes
Nuclear charge radii globally scale with atomic mass number A as A1∕3, and isotopes with an odd number of neutrons are usually slightly smaller in size than their even-neutron neighbours. This odd–even staggering...

Systematics of toroidal dipole modes in Ca, Ni, Zr, and Sn isotopes
We analyze the relation between isoscalar toroidal modes and so-called pygmy dipole resonance (PDR), which both appear in the same region of low-energy dipole excitations. To this end, we use a theoretical des...

Proton superfluidity and charge radii in proton-rich calcium isotopes
One of the most important global properties of the atomic nucleus is its size. Experimentally determined nuclear charge radii carry unique information on the nuclear force and complex dynamics of protons and n...

Nuclear density-functional theory and fission of super-heavy elements
We review the prediction of fission properties of super-heavy elements (SHE) by self-consistent mean-field models thereby concentrating on the widely used Skyrme-Hartree-Fock (SHF) approach. We explain briefly...

Towards the Inclusion of Dissipative Effects in Quantum Time-Dependent Mean-Field Theories
We discuss various theoretical approaches to describe dissipative dynamics in finite systems. We focus in particular on the case of irradiated clusters and molecules. We recall semi-classical approaches succes...

Toroidal resonance: Relation to pygmy mode, vortical properties, and anomalous deformation splitting
We review a recent progress in investigation of the isoscalar toroidal dipole resonance (TDR). A possible relation of the TDR and low-energy dipole excitations (also called a pygmy resonance) is analyzed. It i...

The phonon-coupling model for Skyrme forces
A short review on the self-consistent RPA based on the energy-density functional of the Skyrme type is given. We also present an extension of the RPA where the coupling of phonons to the single-particle states...

Toroidal, compression, and vortical dipole strengths in 144-154Sm: Skyrme-RPA exploration of the deformation effect
A comparative analysis of toroidal, compressional and vortical dipole strengths in the spherical 144Sm and the deformed 154Sm is performed within the random-phase approximation using a set of different Skyrme for...

Have superheavy elements been produced in nature?
We discuss the possibility whether superheavy elements can be produced in Nature by the astrophysical rapid neutron capture process. To this end we have performed fully dynamical network r-process calculations...
