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

open access: yesPhotonics, 2022
An important imaging technique in biomedicine, the conventional optical microscopy relies on relatively complicated and bulky lens and alignment mechanics.

Holographic Principle during Inflation and a Lower Bound on Density Fluctuations [PDF]

open access: yes, 1998
We apply the holographic principle during the inflationary stage of our universe. Where necessary, we illustrate the analysis in the case of new and extended inflation which, together, typify generic models of inflation.

Holographic Dark Information Energy

open access: yesEntropy, 2011
Landauer’s principle and the Holographic principle are used to derive the holographic information energy contribution to the Universe. Information energy density has increased with star formation until sufficient to start accelerating the expansion of ...

The traveltime holographic principle [PDF]

open access: yesGeophysical Journal International, 2014
Abstract Fermat's interferometric principle is used to compute interior transmission traveltimes τpq from exterior transmission traveltimes τsp and τsq. Here, the exterior traveltimes are computed for sources s on a boundary B that encloses a volume V of interior points p and q.

Axion mass and quantum information

open access: yesPhysics Letters B, 2018
I present a novel way of linking the shift in the axion mass due to non-perturbative gravitational effects and the quantum information interpretation of the holographic principle.

Entropy and holography constraints for inhomogeneous universes [PDF]

open access: yes, 2000
We calculated the entropy of a class of inhomogeneous dust universes. Allowing spherical symmetry, we proposed a holographic principle by reflecting all physical freedoms on the surface of the apparent horizon.

Understanding the holographic principle via RG flow [PDF]

open access: yes, 2016
This is a review of some recent works which demonstrate how the classical equations of gravity in AdS themselves hold the key to understanding their holographic origin in the form of a strongly coupled large $N$ QFT whose algebra of local operators can ...

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
