Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Constraining quadrupole deformations with relativistic effects
European Physical Journal C: Particles and FieldsWe investigate two general relativistic effects—namely, the Shirokov and Shapiro effects—within the framework of the Zipoy–Voorhees spacetime (q-metric), which generalizes the Schwarzschild solution by incorporating a quadrupole moment.

Analysis of transverse beam stabilization with radio frequency quadrupoles
Physical Review Accelerators and Beams, 2017 A radio frequency (rf) quadrupole has been considered as a potential alternative device for Landau damping in circular hadron colliders. The objective of this study is to benchmark and confirm its stabilizing effect predicted by stability diagram theory ...

Advanced Materials, EarlyView.ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of
