Comparison of holographic photopolymer materials by use of analytic nonlocal diffusion models [PDF]

, 2002
The one-dimensional diffusion equation governing holographic grating formation in photopolymers, which includes both nonlocal material response and generalized dependence of the rate of polymerization on the illuminating intensity, has been previously ...

Holographic action principle for TT¯-deformation

Physics Letters B
We explore the action principle for the holographic TT¯-deformation. We develop a scheme in which one can holographically reproduce the action of the Liouville theory deformed by TT¯-insertion.

Holographic cosmology from “dimensional reduction” of N = 4 SYM vs. AdS5 × S 5

Journal of High Energy Physics, 2019
We propose a way to obtain holographic cosmology models for 3+1 dimensional cosmologies vs. 3 dimensional field theories from a “dimensional reduction” procedure, obtained by integrating over the time direction, of (modifed) standard holographic duals of

Bamboo‐Slip‐Inspired Conformal Reconfigurable Metasurfaces

Advanced Science, EarlyView.
Bamboo‐slip‐inspired conformal reconfigurable metasurface system. The structure is mainly composed of three parts, which are conformal metasurface, pattern reconfigurable antenna, and control components (such as Field Programmable Gate Array (FPGA)). Conformal metasurfaces draw inspiration from the design of ancient Chinese bamboo slips.

Aspects of Holographic Superconductivity [PDF]

, 2012
In this thesis we study two different aspects of holographic superconductivity. First we study fully backreacting Gauss-Bonnet (GB) holographic superconductors in 5 bulk spacetime dimensions. We explore the system’s dependence on the scalar mass for both

Efficient Cholesteric Liquid Crystal Waveguide Polarizing Splitters for High‐Sensitivity Chip‐Scale Atomic Magnetometry

Advanced Science, EarlyView.
An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

Total internal reflection coupling module for generating zero-order-free holographic optical fields [PDF]

APL Photonics
The liquid crystal spatial light modulator (LC-SLM) is a widely utilized device for optical field modulation. However, it is commonly plagued by the significant zero-order beam in the output diffraction pattern.

Deep‐Learning‐Based Denoising for Improved Phase Precision in Electron Holography of Electromagnetic Fields in Nanoscale Materials

Advanced Science, EarlyView.
Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.
