A real-space, real-time implementation of time-dependent density functional theory is used to study
electron field emission from nanostructures. Carbon nanotubes and graphene nanoribbons are used as
model systems. The ...
Variational calculations of the ground state of positronium hydride (HPs) are reported, including various expectation values, electron-positron annihilation rates, and leading relativistic corrections to the total and ...

Time-dependent density functional theory simulation of laser-induced ionization is presented. Various test
systems including a small wire-like molecule, C12H14, as well as carbon nanotubes with varying diameter are
studied. ...
Field ionization and Coulomb explosion of small hydrocarbon molecules driven by intense laser pulses are studied in a combined theoretical and experimental framework. The spectra of ejected protons calculated by the ...
