Holographic principle, cosmological constant and cyclic cosmology [PDF]
Modern Physics Letters A, 2019 The holographic principle provides a deep insight into quantum gravity and resolves the fine-tuning crisis concerning the cosmological constant. Holographic dark energy introduces new ultraviolet (UV) and infrared (IR) cutoffs into quantum gravity which are necessarily strongly related.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Explaining Holographic Dark Energy
Galaxies, 2013 The possible holographic origin of dark energy is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al., Thomas’ bulk holography argument, and Ng’s spacetime foam argument, are shown to be not wholly ...

PRINCIPLES OF HOLOGRAPHIC TECHNOLOGIES
, 2023 Like virtual reality, holographic technology is capable of providing a more immersive visual experience by creating three-dimensional images of people, places, and objects. Holography is a method of obtaining threedimensional, realistic images. For their creation, laser technology is used instead of a camera.

Three flavour QCD from the holographic principle [PDF]
Journal of High Energy Physics, 2006 Building on recent research into five-dimensional holographic models of QCD, we extend this work by including the strange quark with an SU(3)_L\times SU(3)_R gauge symmetry in the five-dimensional theory. In addition we deform the naive $AdS$ metric with a single parameter, thereby breaking the conformal symmetry at low energies.
