We present the results of an ongoing investigation designed to measure the forbidden magnetic dipole transition amplitude for the 6s2 S0 → 6s5d D1 transition (408 nm) in atomic ytterbium. The transition is excited in an effusive atiomic beam with a C.W. laser in the presence of crossed D.C. electric and magnetic fields. The fields are arranged to provide interference between the magnetic dipole...

A double E-shaped toroidal dipole metasurface is designed with the high Q-factor Fano and classical electromagnetically induced transparency (EIT) phenomena in microwave frequency range. With introduction of an asymmetric structure, sharp resonance can be excited acquired a quite 134 at lower 4.58 GHz. It numerically experimentally demonstrated that singularity response construction caused by i...

Polymer solar cells (PSCs) with different anode buffer layers were fabricated to investigate dipoleassisted hole extraction on the performance improvement of PSCs. The power conversion efficiency (PCE) of PSCs was increased from 4.77% to 6.18% with 29.6% improvement due to the increased short circuit current density (Jsc) from 12.00 to 15.65 mA/cm 2 induced by the oriented LiF dipole-assisted h...

The limit of decreasing laser frequency cannot be considered independently from nondipole effects due to the increase in laser-induced continuum electron speed this limit. Therefore, work, tunneling ionization adiabatic is for an effective field that includes beyond electric-dipole term first order $1/c$, with $c$ being light. describes interaction resulting electric dipole-induced velocity and...

Pt(ii) phenylbipyridine complexes possessing bis(phenylisoxazolyl)phenylacetylene ligands self-assembled to form stacked aggregates via Pt-Pt, π-π stacking, and dipole-dipole interactions. The assembled structures were influenced by the solvent properties. Non-helical assemblies found in chloroform displayed metal-metal-to-ligand charge transfer absorption and emission, whereas helical assembli...
