Krylov Complexity in Quantum Field Theory

open access: yesNuclear Physics B, 2023
In this paper, we study the Krylov complexity in quantum field theory and make a connection with the holographic “Complexity equals Volume” conjecture.

Volume holographic interconnections with maximal capacity and minimal cross talk [PDF]

open access: yes, 1989
Optical interconnections utilizing volume holography are described. Intrinsic cross-talk effects that limit the number of independent interconnections are identified and analyzed by applying coupled-wave analysis.

A holographic system for subsea recording and analysis of plankton and other marine particles [PDF]

open access: yes, 2003
We report here details of the design, development, initial testing and field-deployment of the HOLOMAR system for in-situ subsea holography and analysis of marine plankton and nonliving particles.

Imaging of Volume Phase Gratings in a Photosensitive Polymer, Recorded in Transmission and Reflection Geometry

open access: yesApplied Sciences, 2014
Volume phase gratings, recorded in a photosensitive polymer by two-beam interference exposure, are studied by means of optical microscopy. Transmission gratings and reflection gratings, with periods in the order of 10 μm down to 130 nm, were investigated.

Holographic particle localization under multiple scattering [PDF]

open access: yes, 2019
We introduce a novel framework that incorporates multiple scattering for large-scale 3D particle-localization using single-shot in-line holography. Traditional holographic techniques rely on single-scattering models which become inaccurate under high ...

Application of Lippmann interference photography to data storage [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2008
Lippmann’s interference photography is an elegant process to record coloured images in the volume of a sensitive material. We propose to use this technique for wavelength multiplexed data storage in a page-oriented approach.

Study of Full-Color Multiplexed Transmission Holograms of Diffusing Objects Recorded in Photopolymer Bayfol HX

open access: yesPhotonics, 2021
A wavelength multiplexing procedure for color transmission volume holograms of diffusing objects recorded in Bayfol® HX200 photopolymer is proposed. For the recording, three lasers of 442 nm, 532 nm and 633 nm, and a Spectralon® diffusing object were ...
