Facts and Fictions about Anti deSitter Spacetimes with Local Qantum Matter
, 2001 It is natural to analyse the AdS$_{d+1}$-CQFT$_{d}$ correspondence in the context of the conformal- compactification and covering formalism. In this way one obtains additional inside about Rehren's rigorous algebraic holography in connection with the ...

Moyal Quantization, Holography, and the Quantum Geometry of Surfaces [PDF]
, 1998 An elementary introduction is provided to the phase space quantization method of Moyal and Wigner. We generalize the method so that it applies to 2-dimensional surfaces, where it has an interesting connection with quantum holography.

Classical and Quantum Gravity, 2000 A new version of holographic principle for cosmology is proposed, which dictates that particle entropy within `cosmological apparent horizon' should not exceed gravitational entropy associated with the apparent horizon. It is shown that, in the Friedman-Robertson-Walker (FRW) cosmology, the open Universe as well as a restricted class of flat cases are ...

Modeling and Improving Geometric Accuracy in Projection Multiphoton Lithography
Advanced Optical Materials, EarlyView.A numerical framework describing the optical and photochemical processes is developed to elucidate the origins of geometric deviations in projection multiphoton lithography. The results indicate that oxygen diffusion and inhibition, and DMD diffraction, lead to geometric distortions.

Inflation, holography, and the choice of vacuum in de Sitter space
, 2002 A family of de Sitter vacua introduced in hep-th/0203198 as plausible initial conditions for inflation, are discussed from the point of view of de Sitter holography. The vacua are argued to be physically acceptable and the inflationary picture provides a

Localization & exact holography [PDF]
Journal of High Energy Physics, 2013 Abstract We consider the AdS 2 /CFT 1 holographic correspondence near the horizon of big four-dimensional black holes preserving four supersymmetries in toroidally compactified Type-II string theory.

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation
Advanced Photonics Research, EarlyView.Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

The artistic use of parallax and lenses revealing the invisible in holography [PDF]
, 2012 There are many artistic resources offered by holography: third-dimension registration and reconstruction, immateriality, color interpretation, holographic space, realism, etc.
