Ionization of helium by slow antiproton impact: total and differential cross sections
S. Borbély, J. Feist, S. Nagele +3
We theoretically investigate the single and double ionization of the He atom by antiproton impact for projectile energies ranging from ~keV up to ~keV. We obtain accurate…
Reflection resonances in surface-disordered waveguides: strong higher-order effects of the disorder
J. Doppler, J. A. Méndez-Bermúdez, J. Feist +5
We study coherent wave scattering through waveguides with a step-like surface disorder and find distinct enhancements in the reflection coefficients at well-defined resonance value…
Thermalization and Cooling of Plasmon-Exciton Polaritons: Towards Quantum Condensation
S. R. K. Rodriguez, J. Feist, M. A. Verschuuren +2
We present indications of thermalization and cooling of quasi-particles, a precursor for quantum condensation, in a plasmonic nanoparticle array. We investigate a periodic array of…
Multi-electron transitions induced by neutron impact on helium
M. Liertzer, J. Feist, S. Nagele +1
We explore excitation and ionization by neutron impact as a novel tool for the investigation of electron-electron correlations in helium. We present single and double ionization sp…
A general approach to few-cycle intense laser interactions with complex atoms
X. Guan, O. Zatsarinny, K. Bartschat +3
A general {\it ab-initio} and non-perturbative method to solve the time-dependent Schrödinger equation (TDSE) for the interaction of a strong attosecond laser pulse with a general…
