Quantum vacuum forces dictate the interaction between individual atoms and dielectric surfaces at nanoscale distances. For example, their large strengths typically overwhelm externally applied forces, which makes it challenging to controllably interface cold atoms with nearby nanophotonic systems. Here we theoretically show that it is possible to tailor the vacuum forces themselves to provide s...

Chloride (from PbCl2 or CH3NH3Cl) has been reported to improve the morphology of perovskite thin film and power conversion efficiency (PCE) of corresponding perovskite solar cells (PSCs). However, the mechanism why chloride functions well in perovskite is unclear. In this work, we investigate the effects of chloric additive (from CH3NH3Cl) on the morphology, diffusion length, and trap state of ...

We report on a simple anisotropic magneto-optical trap for neutral atoms that produces a large sample of cold atoms confined in a cylindrically-shaped volume with a high aspect ratio (100:1). Due to the large number of trapped atoms, the laser beams that propagate along the optically thick axis of the trap to cool the atoms are substantially attenuated. We demonstrate that the resulting intensi...

The measurement and comparison of the magnetic moment (or g-factor) of the proton and antiproton provide a stringent experimental test of the CPT-theorem in the baryonic sector [1]. We set up an experiment for the first selfcontained and direct high-precision measurement of the gfactor of a single isolated proton stored in a Penning trap [2]. In previous experiments the g-factor was determined ...

Sixteen years of archived tufted apple bud moth, Platynota idaeusalis (Walker), trap capture data were compared with archived fruit injury data collected at the Penn State University Fruit Research and Extension Center to define the relationship of trap capture to fruit injury. Pheromone trap capture until 15 June was the best predictor of fruit injury at harvest. Using the regression equation ...
