Tensor representation of quadrupole expansion for softened potentials in N-body simulations
, 2023 A tensor representation for quadrupole expansion is proposed as a recipe for n-body simulations of collisionless stellar systems that do not perform the direct summation method, as is the case of TREECODE.

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 ...

Photoassociation of a cold-atom–molecule pair: Long-range quadrupole-quadrupole interactions
, 2010 The general formalism of the multipolar expansion of electrostatic interactions is applied to the calculation of the potential energy between an excited atom (without fine structure) and a ground-state diatomic molecule at large mutual separations.

Enhancement of specular behavior in atom mirrors with quadrupole-active transitions
, 2023 Modern studies have confirmed the possibility of making atomic mirrors using quadrupole-active atomic transition evanescent waves. The reflection process has been shown to be enhanced to approach specular behavior in several ways.

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

Derivation of the radial dependence of the quadrupole force from a Woods-Saxon potential
Nuclear Physics A, 1970 Abstract For use in calculation of collective quadrupole phenomena we construct a modified quadrupole force, whose radial dependence is related to that of a Woods-Saxon well. Matrix elements and self-consistent interaction strengths are compared to those of the usual quadrupole force, which is based on a harmonic oscillator potential.

Quadrupole topological phases in the zero-dimensional optical cavity
, 2020 The quadrupole topological insulator, which supports robust corner states, has been recently demonstrated in two-dimensional (2D) spatial lattices. Here, we design the first photonic quadrupole topological insulator in fully synthetic spaces with the ...

Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry
Advanced Materials, EarlyView.Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...

Advanced Materials, EarlyView.We introduce a computational workflow that combines quantum chemical calculations and machine learning techniques to predict the catalytic performance of a wide range of catalysts in the nitrogen reduction reaction (NRR). The analysis of the trained models provides insights into the complex structure–activity relationship in experimental catalytic ...
