High-contrast, speckle-free, true 3D holography via binary CGH optimization [PDF]
Holography is a promising approach to implement the three-dimensional (3D) projection beyond the present two-dimensional technology. True 3D holography requires abilities of arbitrary 3D volume projection with high-axial resolution and independent ...

Imaging biological tissue with high-throughput single-pixel compressive holography
Single-pixel holography generates holographic images with a single-pixel detector making this relatively inexpensive. Here the authors report a high-throughput single-pixel compressive holography method for imaging biological tissue which can either ...

Decimeter-depth and polarization addressable color 3D meta-holography [PDF]
Fueled by the rapid advancement of nanofabrication, metasurface has provided unprecedented opportunities for 3D holography. Large depth 3D meta-holography not only greatly increases information storage capacity, but also enables distinguishing of the ...

Carrollian Perspective on Celestial Holography. [PDF]
We show that a 3D sourced conformal Carrollian field theory has the right kinematic properties to holographically describe gravity in 4D asymptotically flat spacetime. The external sources encode the leaks of gravitational radiation at null infinity. The

Bridging Carrollian and celestial holography [PDF]
Gravity in $4d$ asymptotically flat spacetime constitutes the archetypal example of a gravitational system with leaky boundary conditions. Pursuing our analysis of [1], we argue that the holographic description of such a system requires the coupling of ...

Celestial holography meets twisted holography: 4d amplitudes from chiral correlators [PDF]
We propose a new program for computing a certain integrand of scattering amplitudes of four-dimensional gauge theories which we call the form factor integrand, starting from 6d holomorphic theories on twistor space.

Noninvertible Symmetries from Holography and Branes. [PDF]
We propose a systematic approach to deriving symmetry generators of quantum field theories in holography. Central to this analysis are the Gauss law constraints in the Hamiltonian quantization of symmetry topological field theories (SymTFTs), which are ...

Optical secret sharing with cascaded metasurface holography [PDF]
The secret of a holographic image can be shared across two closely stacked metasurface holograms. Secret sharing is a well-established cryptographic primitive for storing highly sensitive information like encryption keys for encoded data.
