Scattering resonances in slow NH-He collisions
Koos B. Gubbels, Sebastiaan Y. T. van de Meerakker, Gerrit C. Groenenboom +2
We theoretically study slow collisions of NH molecules with He atoms, where we focus in particular on the observation of scattering resonances. We calculate state-to-state inte…
Assessment of correlation energies based on the random-phase approximation
Joachim Paier, Xinguo Ren, Patrick Rinke +4
The random-phase approximation to the ground state correlation energy (RPA) in combination with exact exchange (EX) has brought Kohn-Sham (KS) density functional theory one step cl…
Strong electronic correlation in the Hydrogen chain: a variational Monte Carlo study
Lorenzo Stella, Claudio Attaccalite, Sandro Sorella +1
In this article, we report a fully ab initio variational Monte Carlo study of the linear, and periodic chain of Hydrogen atoms, a prototype system providing the simplest example of…
Correlation potentials for molecular bond dissociation within the self-consistent random phase approximation
M. Hellgren, D. R. Rohr, E. K. U. Gross
Self-consistent correlation potentials for H and LiH for various inter-atomic separations are obtained within the random phase approximation (RPA) of density functional theory.…
Momentum dependent ultrafast electron dynamics in antiferromagnetic EuFe2As2
L. Rettig, R. Cortes, S. Thirupathaiah +5
Employing the momentum-sensitivity of time- and angle-resolved photoemission spectroscopy we demonstrate the analysis of ultrafast single- and many-particle dynamics in antiferroma…

Janneke H. Blokland, Jens Riedel, Stephan Putzke +3
Carbon monoxide molecules in their electronic, vibrational, and rotational ground state are highly attractive for trapping experiments. The optical or ac electric traps that can be…
Otto Stern (1888-1969): The founding father of experimental atomic physics
J. Peter Toennies, Horst Schmidt-Böcking, Bretislav Friedrich +1
We review the work and life of Otto Stern who developed the molecular beam technique and with its aid laid the foundations of experimental atomic physics. Among the key results of…
Fast and Accurate Modeling of Molecular Atomization Energies with Machine Learning
Matthias Rupp, Alexandre Tkatchenko, Klaus-Robert Müller +1
We introduce a machine learning model to predict atomization energies of a diverse set of organic molecules, based on nuclear charges and atomic positions only. The problem of solv…
Design of Oscillator Networks with Enhanced Synchronization Tolerance against Noise
Tatsuo Yanagita, Alexander S. Mikhailov
Can synchronization properties of a network of identical oscillators in the presence of noise be improved through appropriate rewiring of its connections? What are the optimal netw…
Interaction between polar molecules subject to a far-off-resonant optical field: Entangled dipoles up- or down-holding each other
Mikhail Lemeshko, Bretislav Friedrich
We show that the electric dipole-dipole interaction between a pair of polar molecules undergoes an all-out transformation when superimposed by a far-off resonant optical field. The…
Time-dependent density-functional and reduced density-matrix methods for few electrons: Exact versus adiabatic approximations
N. Helbig, J. I. Fuks, I. V. Tokatly +3
To address the impact of electron correlations in the linear and non-linear response regimes of interacting many-electron systems exposed to time-dependent external fields, we stud…

The electronic structure of graphene on Cu(111) and Cu(100) single crystals is investigated using low energy electron microscopy, low energy electron diffraction and angle resolved…
Entanglement of polar symmetric top molecules as candidate qubits
Qi Wei, Sabre Kais, Bretislav Friedrich +1
Proposals for quantum computing using rotational states of polar molecules as qubits have previously considered only diatomic molecules. For these the Stark effect is second-order,…

Recently, a decelerator for neutral polar molecules has been presented that operates on the basis of macroscopic, three-dimensional, traveling electrostatic traps (Osterwalder et a…
Effective screening and the plasmaron bands in Graphene
Andrew L. Walter, Aaron Bostwick, Ki-Joon Jeon +10
Electron-plasmon coupling in graphene has recently been shown to give rise to a "plasmaron" quasiparticle excitation. The strength of this coupling has been predicted to depend on…
