Assessment of Dressed Time-Dependent Density-Functional Theory for the Low-Lying Valence States of 28 Organic Chromophores
Miquel Huix-Rotllant, Andrei Ipatov, Angel Rubio +1
Almost all time-dependent density-functional theory (TDDFT) calculations of excited states make use of the adiabatic approximation, which implies a frequency-independent exchange-c…
Magneto-electric point scattering theory for metamaterial scatterers
I. Sersic, C. Tuambilangana, T. Kampfrath +1
We present a new, fully analytical point scattering model which can be applied to arbitrary anisotropic magneto-electric dipole scatterers, including split ring resonators (SRRs),…
To wet or not to wet? Dispersion forces tip the balance for water-ice on metals
Javier Carrasco, Biswajit Santra, Jiří Klimeš +1
Despite widespread discussion, the role of van der Waals dispersion forces in wetting remains unclear. Here we show that non-local correlations contribute substantially to the wate…
Magnetism in C or N-doped MgO and ZnO: density-functional study of impurity pairs
Hua Wu, Alessandro Stroppa, Sung Sakong +3
It is shown that substitution of C or N for O recently proposed as a way to create ferromagnetism in otherwise nonmagnetic oxide insulators is curtailed by formation of impurity pa…
Driving rotational transitions in molecules on a chip
Gabriele Santambrogio, Samuel A. Meek, Mark J. Abel +2
Polar molecules in selected quantum states can be guided, decelerated, and trapped using electric fields created by microstructured electrodes on a chip. Here we explore how transi…
Ultrafast changes in lattice symmetry probed by coherent phonons
Simon Wall, Daniel Wegkamp, Laura Foglia +4
The electronic and structural properties of a material are strongly determined by its symmetry. Changing the symmetry via a photoinduced phase transition offers new ways to manipul…
Momentum-Resolved Ultrafast Electron Dynamics in Superconducting Bi2Sr2CaCu2O8+delta
R. Cortes, L. Rettig, Y. Yoshida +3
The non-equilibrium state of the high-Tc superconductor Bi2Sr2CaCu2O8+delta and its ultrafast dynamics have been investigated by femtosecond time- and angle-resolved photoemission…
Beyond the Random Phase Approximation for the Electron Correlation Energy: The Importance of Single Excitations
Xinguo Ren, Patrick Rinke, Alexandre Tkatchenko +1
The random phase approximation (RPA) for the electron correlation energy, combined with the exact-exchange energy, represents the state-of-the-art exchange-correlation functional w…
Multiple packets of neutral molecules revolving for over a mile
Peter C. Zieger, Sebastiaan Y. T. van de Meerakker, Cynthia E. Heiner +3
The level of control that one has over neutral molecules in beams dictates their possible applications. Here we experimentally demonstrate that state-selected, neutral molecules ca…
Spatial corrugation and bonding of single layer graphene on Rh(111)
M. Fonin, M. Sicot, O. Zander +6
Topographic scanning tunneling microscopy (STM) images of epitaxial single layer graphene on the Rh(111) surface reveal that extended single crystalline graphene domains are produc…
Catching proteins in liquid helium droplets
Frauke Bierau, Peter Kupser, Gerard Meijer +1
An experimental approach is presented that allows for the incorporation of large mass/charge selected ions in liquid helium droplets. It is demonstrated that droplets can be effici…
State- and conformer-selected beams of aligned and oriented molecules for ultrafast diffraction studies
Frank Filsinger, Gerard Meijer, Henrik Stapelfeldt +2
The manipulation of the motion of neutral molecules with electric or magnetic fields has seen tremendous progress over the last decade. Recently, these techniques have been extende…
Electronic and magnetic properties of the graphene-ferromagnet interface
Yu. S. Dedkov, M. Fonin
The article presents the work on the investigation of the surface structure as well as electronic and magnetic properties of graphene layer on a lattice matched surface of a ferrom…
Giant Faraday rotation in single- and multilayer graphene
Iris Crassee, Julien Levallois, Andrew L. Walter +6
Optical Faraday rotation is one of the most direct and practically important manifestations of magnetically broken time-reversal symmetry. The rotation angle is proportional to the…
Ionization of oriented carbonyl-sulfide molecules by intense circularly polarized laser pulses
Darko Dimitrovski, Mahmoud Abu-samha, Lars Bojer Madsen +7
We present combined experimental and theoretical results on strong-field ionization of oriented carbonyl-sulphide molecules by circularly-polarized laser pulses. The obtained molec…
Ionization of 1D and 3D oriented asymmetric top molecules by intense circularly polarized femtosecond laser pulses
Jonas L. Hansen, Lotte Holmegaard, Line Kalhøj +9
We present a combined experimental and theoretical study on strong-field ionization of a three-dimensionally oriented asymmetric top molecule, benzonitrile (CHN), by circul…
Microwave Lens for Polar Molecules
Hitoshi Odashima, Simon Merz, Katsunari Enomoto +2
We here report on the implementation of a microwave lens for neutral polar molecules suitable to focus molecules both in low-field-seeking and in high-field-seeking states. By usin…
Single photon double ionization of the helium dimer
T. Havermeier, T. Jahnke, K. Kreidi +16
We show that a single photon can ionize the two helium atoms of the helium dimer in a distance up to 10 °A. The energy sharing among the electrons, the angular distributions of the…
Interatomic Coulombic Decay following Photoionization of the Helium Dimer: Observation of Vibrational Structure
T. Havermeier, T. Jahnke, K. Kreidi +15
Using synchrotron radiation we simultaneously ionize and excite one helium atom of a helium dimer (He_2) in a shakeup process. The populated states of the dimer ion (i.e. He^[*+](n…
