Holography and phenomenology [PDF]
Journal of High Energy Physics, 2001 We examine various aspects of the conjectured duality between warped AdS$_5$ geometries with boundary branes and strongly coupled (broken) conformal field theories coupled to dynamical gravity. We also examine compactifications with 5-d gauge fields, in which case the holographic dual is a broken CFT weakly coupled to dynamical gauge fields in addition

Holography, and the future of 3D display
Light: Advanced Manufacturing, 2021 The pioneers of holography, Gabor, Leith, Upatnieks, and Denisyuk, predicted very early that the ultimate 3D display will be based on this technique. This conviction was rooted on the fact that holography is the only approach that can render all optical ...

Addressable metasurfaces for dynamic holography and optical information encryption [PDF]
Science Advances, 2018 We present addressable plasmonic metasurfaces for optical information encryption and holography. Metasurfaces enable manipulation of light propagation at an unprecedented level, benefitting from a number of merits unavailable to conventional optical ...

Holography and cosmology [PDF]
Physics Letters B, 1999 We consider a recent generalisation by Bousso of an earlier holography proposal by Fischler and Susskind. We demonstrate that in general inhomogeneous universes such a proposal would involve extremely complicated - possibly fractal - light sheets. Furthermore, in general such a light sheet cannot be known a priori on the basis of theory and moreover ...

Optimization strategies and artifacts of time‐involved small‐angle neutron scattering experiments
Journal of Applied Crystallography, Volume 55, Issue 6, Page 1603-1612, December 2022., 2022 This article reviews the opportunities and limitations of time‐involved small‐angle neutron scattering experiments, with the typical artifacts of the recorded data illustrated by virtue of the response of the skyrmion lattice in MnSi under periodic changes of the direction of the stabilizing field.Kinetic small‐angle neutron scattering provides access ...

Holostereosynthesis: An Improvement to Louis Lumière’s Photostereosynthesis Technique
Applied Sciences, 2022 In 1920, Louis Lumière, one of the fathers of Cinématograph, invented photostereosynthesis, a photography technique that could recreate three-dimensional images without a specific artifice.

Incoherent Digital Holography: A Review
Applied Sciences, 2018 Digital holography (DH) is a promising technique for modern three-dimensional (3D) imaging. Coherent holography records the complex amplitude of a 3D object holographically, giving speckle noise upon reconstruction and presenting a serious drawback ...

Deep learning for digital holography: a review.
Optics Express, 2021 Recent years have witnessed the unprecedented progress of deep learning applications in digital holography (DH). Nevertheless, there remain huge potentials in how deep learning can further improve performance and enable new functionalities for DH.
