Holographic entanglement entropy of semi-local quantum liquids [PDF]

, 2013
We consider the holographic entanglement entropy of $(d+2)$-dimensional semi-local quantum liquids, for which the dual gravity background in the deep interior is $AdS_{2}\times\mathbb{R}^{d}$ multiplied by a warp factor which depends on the radial ...

Holographic three-point functions: one step beyond the tradition [PDF]

, 2003
Within the program of holographic renormalization, we discuss the computation of three-point correlation functions along RG flows. We illustrate the procedure in two simple cases.

Circular holographic video display system

Optics Express, 2011
A circular holographic video display system reconstructs holographic video. Phase-only spatial light modulators are tiled in a circular configuration in order to increase the field of view. A beam-splitter is used to align the active area of the SLMs side by side without any gap. With the help of this configuration observers can see 3D ghost-like image

Holographic Geometry and Noise in Matrix Theory

, 2009
Using Matrix Theory as a concrete example of a fundamental holographic theory, we show that the emergent macroscopic spacetime displays a new macroscopic quantum structure, holographic geometry, and a new observable phenomenon, holographic noise, with ...

Holographic entanglement entropy of a $1+1$ dimensional $p$-wave superconductor [PDF]

, 2017
We examine the behavior of entanglement entropy of a subsystem $A$ in a fully backreacted holographic model of a $1+1$ dimensional $p$ wave superconductor across the phase transition.

Binocular dynamic holographic floating image display

Optics Express, 2021
This paper proposes a binocular holographic floating display. The device consists of two phase-modulation spatial light modulators (SLM) and a dihedral corner reflector array (DCRA) element. The conjugate images of the SLMs generated by the DCRA become the system’s exit pupils.

Ultrathin wide-angle large-area digital 3D holographic display using a non-periodic photon sieve

Nature Communications, 2019
3D holographic displays still face many challenges such as small viewing angle and image size. Here the authors present a scalable method for displaying large holographic images with a wide viewing angle using a wide-angle diffracting element in a flat ...

Measurement of Quantum Fluctuations in Geometry

, 2008
A particular form for the quantum indeterminacy of relative spacetime position of events is derived from the limits of measurement possible with Planck wavelength radiation.

Geometric and physical configurations of meta‐atoms for advanced metasurface holography

InfoMat, 2021
Metasurfaces consisting of subwavelength structures, so‐called meta‐atoms, have steadily attracted considerable attention for advanced holography due to their advantages in terms of high‐resolution holographic images, large field of view, and compact ...
