Journal ArticleDOI
Multiconfiguration linear response approach to the calculation of parity violating potentials in polyatomic molecules
Robert Berger,Martin Quack +1 more
TL;DR: In this paper, a multiconfiguration linear response approach to electroweak quantum chemistry including effects from the parity violating weak nuclear force is presented, where the parity violation potential (Epv) is introduced by the linear response function and by solving the response equations in a direct iterative manner.
Journal ArticleDOI
Locality and Fluctuations: Trends in Imidazolium-Based Ionic Liquids and Beyond
Katharina Wendler,Stefan Zahn,Florian Dommert,Robert Berger,Christian Holm,Barbara Kirchner,Luigi Delle Site +6 more
TL;DR: Going beyond imidazolium-based systems, it is found that even for the protic ionic liquid monomethyl ammonium nitrate, the same features hold, representing a strong support to the hypothesis of rattling ions in long-living ion cages proposed in the last years.
Journal ArticleDOI
A comparative study of two classical force fields on statics and dynamics of [EMIM][BF4] investigated via molecular dynamics simulations
Florian Dommert,Jochen Schmidt,Baofu Qiao,Yuan-yuan Zhao,Christian Krekeler,Luigi Delle Site,Robert Berger,Christian Holm +7 more
TL;DR: Both force fields underestimate the zero-field electrical conductivity, while the experimental dielectric constant can be reproduced within the expected statistical error boundaries.
Journal ArticleDOI
Heptacene: Characterization in Solution, in the Solid State, and in Films.
Ralf Einholz,Treliant Fang,Robert Berger,Robert Berger,Peter Grüninger,Andreas Früh,Thomas Chassé,Reinhold F. Fink,Holger F. Bettinger +8 more
TL;DR: Monitoring this cycloreversion by solid state 13C cross-polarized magic angle spinning NMR reveals that solid heptacene has a half-life time of several weeks at room temperature.
Journal ArticleDOI

Ricketts,Sebastian Rothe,Lutz Schweikhard,A. R. Vernon,Klaus Wendt,Frank Wienholtz,Frank Wienholtz,Shane Wilkins,Xiaofei Yang +29 more
TL;DR: An experimental approach to studying short-lived radioactive molecules, which allows us to measure molecules with lifetimes of just tens of milliseconds and provides evidence of the existence of a suitable laser-cooling scheme for these molecules and represents a key step towards high-precision studies in these systems.
