Generalized Holographic Principle, Gauge Invariance and the Emergence of Gravity à la Wilczek

open access: yesFrontiers in Astronomy and Space Sciences, 2021
We show that a generalized version of the holographic principle can be derived from the Hamiltonian description of information flow within a quantum system that maintains a separable state. We then show that this generalized holographic principle entails

Goursat's problem and the holographic principle [PDF]

open access: yesNuclear Physics B, 2004
The whole idea of holography as put forward by Gerard 't Hooft assumes that data on a boundary determine physics in the volume. This corresponds to a Dirichlet problem for euclidean signature, or to a Goursat (characteristic) problem in the lorentzian setting. Is this last aspect of the problem that is explored here for Ricci flat spaces with vanishing

Holographic mensuration of suspended particles in aquatic systems [PDF]

open access: yes, 1995
The distribution and dynamics of aggregates in the aquatic environment play an important role in the modelling of biogeochemical processes. Previous work on aggregates in the ocean (e.g.

Resolution and Contrast Enhancement for Lensless Digital Holographic Microscopy and Its Application in Biomedicine

open access: yesPhotonics, 2022

Entropic uncertainty principle, partition function and holographic principle derived from Liouville’s Theorem

open access: yesPhysics Open, 2021
An entropic version of Liouville’s Theorem is defined in terms of the conjugate variables (“hyperbolic position” and “entropic momentum”) of an entropic Hamiltonian. It is used to derive the Holographic Principle as applied to holomorphic structures that

Holographic principle and string cosmology [PDF]

open access: yesClassical and Quantum Gravity, 1999
String cosmology is revisited from cosmological viewpoint of holographic principle put forward by `t Hooft, and by Fischler and Susskind. It is shown that the holography requires existence of a `graceful exit' mechanism, which renders the Universe nonsingular by connecting pre- and post-big bang phases smoothly.
