Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop
Laser &Photonics Reviews, EarlyView.Neural network and optimization‐based approaches are introduced for Orbital Angular Momentum (OAM) multiplexed holography, enabling high‐capacity, phase‐only image reconstruction. A Camera‐In‐The‐Loop (CITL) system learns a realistic propagation model to correct system imperfections.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
physica status solidi (RRL) – Rapid Research Letters, EarlyView.The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Recent advances in atomic resolution three-dimensional holography
Advances in Physics: XThree-dimensional (3D) local atomic structure around specific functional atom plays a crucial role in functional materials, but it has not been able to be analyzed by a standard structure analysis method of x-ray diffraction (XRD) because this kind of ...

Dipole Determination by Polarimetric Spectroscopy Yielding the Orientation of Gold Nanorods
Small Science, EarlyView.An all‐spectroscopic method is established to extract the azimuthal orientation of electric dipoles excited within gold nanorods of various aspect ratios. By using an analytical dipole model in combination with polarimetric measurements that analyze the interplay between the structure's eigenmodes, an excellent orientation precision of ±2.45° is ...

Small Methods, EarlyView.Analytical ultracentrifugation (AUC) is a powerful tool for studying the size–property relationships of nanomaterials in their native environment. A methodology based on AUC with in‐line multiwavelength emission detection is developed, enabling the measurement of the size‐resolved emission spectra of giant‐shell CdSe/CdS quantum dots.
