An exact construction of codimension two holography [PDF]
Journal of High Energy Physics, 2021 Recently, a codimension two holography called wedge holography is proposed as a generalization of AdS/CFT. It is conjectured that a gravitational theory in d + 1 dimensional wedge spacetime is dual to a d − 1 dimensional CFT on the corner of the wedge ...

Dual-comb hyperspectral digital holography [PDF]
Nature Photonics 15, 890-894 (2021), 2021 Holography1 has always held special appeal as it is able to record and display spatial information in three dimensions2–10. Here we show how to augment the capabilities of digital holography11,12 by using a large number of narrow laser lines at precisely

Holography of information in AdS/CFT [PDF]
Journal of High Energy Physics, 2022 The principle of the holography of information states that in a theory of quantum gravity a copy of all the information available on a Cauchy slice is also available near the boundary of the Cauchy slice.

Cone holography with Neumann boundary conditions and brane-localized gauge fields [PDF]
Journal of High Energy Physics, 2023 Cone holography is a codimension-n doubly holographic model, which can be interpreted as the holographic dual of edge modes on defects. The initial model of cone holography is based on mixed boundary conditions. This paper formulates cone holography with

Towards real-time photorealistic 3D holography with deep neural networks
Nature, 2021 The ability to present three-dimensional (3D) scenes with continuous depth sensation has a profound impact on virtual and augmented reality, human–computer interaction, education and training.

Super-resolution orbital angular momentum holography
Nature Communications, 2023 The resolution of orbital angular momentum holography is limited by a fundamental sampling criterion. Here, the authors break the resolution barrier by temporal multiplexing of binary holograms and enhance the resolution and capacity by several times ...

Factorization and global symmetries in holography [PDF]
SciPost Physics, 2022 We consider toy models of holography arising from 3d Chern-Simons theory. In this context a duality to an ensemble average over 2d CFTs has been recently proposed. We put forward an alternative approach in which, rather than summing over bulk geometries,

Design of broadband terahertz vector and vortex beams: II. Holographic assessment
Light: Advanced Manufacturing, 2022 In this paper, we demonstrate the capabilities of the terahertz pulse time-domain holography in visualisation, simulation, and assessment of broadband THz vortex beam formation dynamics upon its shaping by elements of beam converter, and further ...

Design of broadband terahertz vector and vortex beams: I. Review of materials and components
Light: Advanced Manufacturing, 2022 In this paper, we review the existing approaches for vortex and vector beam shaping and generation in the terahertz frequency range. The particular focus of this review is on the possibility of homogeneous topological charge formation in the ultra-wide ...
