We consider a family of holographically dual models of superconductivity to test the robustness of holographic superconductor models in general. Following the treatment of Hartnoll et al. and Albrecht et al., we introduce the basic holographic model and then develop a family of similar models by varying a parameter in the spacetime metric of the holographic theory. We then calculate several obs...

We describe a superparallel holographic optical correlator that performs two-dimensional spatial and angular multiplexing simultaneously. The key step in this architecture is the use of a holographic multiplexer to split a query image into many copies before it applies them to the holographic database. A holographic demultiplexer, in conjunction with an aperture, is used to identify the locatio...

We present a holographic dark energy model of the universe considering modified generalized Chaplygin gas (GCG). The modified GCG behaves as an ordinary barotropic fluid in the early epoch when the universe was tiny but behaves subsequently as a ΛCDM model at late epoch. An equivalent model with scalar field is obtained here by constructing the corresponding potential. The holographic dark ener...

Photopolymers that absorb in the visible spectrum are useful for different applications such as in the development of holographic memories, holographic optical elements or as holographic recording media. Photopolymers have an undesirable feature, the toxicity of their components and their low environmental compatibility, particularly if we analyse the life cycle of the devices made with these m...

In this paper we consider the holographic model of interacting dark energy in non-flat universe. With the choice of c ≤ 0.84, the interacting holographic dark energy can be described by a phantom scalar field. Then we show this phantomic description of the holographic dark energy with c ≤ 0.84 and reconstruct the potential of the phantom scalar field.

This paper numerically investigates the feasibility of lensless zoomable holographic multiple projections to tilted planes. We have already developed lensless zoomable holographic single projection using scaled diffraction, which calculates diffraction between parallel planes with different sampling pitches. The structure of this zoomable holographic projection is very simple because it does no...

As a continuation of our previous works studying the holographic principle in the planewave limit, we discuss the 3-point correlation functions of BMN operators with bosonic excitations when impurities are not conserved. We show that our proposal for a holographic mapping between the conformal OPE coefficients of super Yang-Mills theory and the 3-point vertex of the holographic string field the...

We present the achievement of the european PHIFE project (Pulsed Holographic Interferometer for the analysis of Fast Events) concerning the development of holographic head principles connected to a YAG Q-switch double pulsed laser. Based on the results of a first laboratory development phase, a final prototype has been designed and built that incorporates both the laser and a modular holographi...
