Development of a Holographic Directional Volumetric Display

IEEE Access
In previous studies, we introduced a directional volumetric display which can project in multiple directions by superimposing different two-dimensional images in three-dimensional space.

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

Colour holography in optics courses at Lund Institute of Technology [PDF]

, 2006
Several physics courses are given at Lund Institute of Technology. In the basic courses on ray and wave optics, holography has played an important role both in stimulating the students to curiously investigate the optical world and as an important ...

Recent advances in atomic resolution three-dimensional holography

Advances 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 ...

Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...

Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

Advanced Science
With the development of nanofabrication technology, meta‐holography has shown unprecedented potential for light regulation. However, due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since

Nested holography

Physical Review D
Recently, we introduced a symmetry on the structure of angular momentum that interchanges internal and external degrees of freedom. The spin-orbit duality is a holographic map that projects a massive theory in four-dimensional flat spacetime onto the three-dimensional S2×R null infinity.

Carbonated Fluorapatite‐Gelatin‐Composites: Morphogenesis and Structure of Kniep's Dumbbells

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
Inspired by the pioneering work of Prof. Rüdiger Kniep on fluorapatite‐gelatin nanocomposites also known as “Kniep's Dumbbells,” this study investigates carbonated fluorapatite‐gelatin aggregates synthesized by the double diffusion technique within a gelatin gel.

Renormalisation Group Flows in Lifshitz Holography [PDF]

, 2011
In this thesis we construct holographic duals of renormalisation group flows between field theories with conformal symmetries and the Lifshitz scaling symmetries.
