Quantum Ghost Imaging by Sparse Spatial Mode Reconstruction

open access: yesAdvanced Quantum Technologies, EarlyView.
Hermite–Gaussian spatial modes are used in quantum ghost imaging for enhanced image reconstruction, by exploiting modal sparsity. By leveraging structured light as a basis for imaging, time‐efficient and high resolution quantum ghost imaging is achieved, paving the way for breakthroughs in low‐light, biological science applications.

High-efficiency, broadband, and low-crosstalk 3D holography by multi-layer holographic-lens integrated metasurface

open access: yesAPL Photonics
Holographic display is considered the holy grail of photorealistic three-dimensional (3D) visualization technology because it can provide arbitrary wavefronts related to the essential visual cues of 3D images.

Recent advances in atomic resolution three-dimensional holography

open access: yesAdvances in Physics: X
Three-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 ...

EASY HOLOGRAPHY [PDF]

open access: yesInternational Journal of Modern Physics D, 2013
It is argued that the role of infinite-dimensional asymptotic symmetry groups in gravity theories are essential for a holographic description of gravity and possibly to a resolution of the black hole information paradox. I present a simple toy model in two-dimensional hyperbolic/anti-de Sitter (AdS) space and describe, by very elementary ...

Dipole Determination by Polarimetric Spectroscopy Yielding the Orientation of Gold Nanorods

open access: yesSmall 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 ...

Analysis of Giant‐Shell CdSe/CdS Quantum Dots via Analytical Ultracentrifugation Combined with Spectrally Resolved Photoluminescence

open access: yesSmall 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.
