Dynamical analysis and statefinder of Barrow holographic dark energy

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Based on the holographic principle and the Barrow entropy, Barrow holographic dark energy had been proposed. In order to analyze the stability and the evolution of Barrow holographic dark energy, we, in this paper, apply the dynamical analysis and ...

Arbitrary Orthogonal Polarization Decomposition and Routing With Complex Amplitude Modulation via Wheel‐of‐Fortune‐Inspired Metasurfaces

open access: yesAdvanced Science, EarlyView.
This work demonstrates a receiver‐transmitter‐integrated metasurface that decomposes an incident wave into orthogonal components and routes them into separate channels. Inspired by a “Wheel‐of‐Fortune” mechanism, it enables independent control over the amplitude, phase, and polarization of the transmitted wave.

Integrated Ultrasonic Platform for Bioelectronic Control through Biological Barriers Based on Metasurface

open access: yesAdvanced Science, EarlyView.
A metasurface‐enabled ultrasonic platform achieves precise multi‐focal control through biological barriers, real‐time physiology‐driven modulation, and simultaneous wireless power and data transmission. By unifying wavefront engineering, closed‐loop feedback, and acoustic communication, this work establishes key enabling technologies toward scalable ...

Holographic Space-Time and Quantum Information

open access: yesFrontiers in Physics, 2020
The formalism of Holographic Space-time (HST) is a translation of the principles of Lorentzian geometry into the language of quantum information. Intervals along time-like trajectories, and their associated causal diamonds, completely characterize a ...

Einstein static universe, GUP, and natural IR and UV cut-offs

open access: yes, 2018
We study the Einstein static universe in the framework of Generalized Uncertainty Principle constructed by the Snyder non-commutative space. It is shown that the deformation parameter can induce an effective energy density subject to GUP which obeys the ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced 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.

Total internal reflection coupling module for generating zero-order-free holographic optical fields [PDF]

open access: yesAPL Photonics
The liquid crystal spatial light modulator (LC-SLM) is a widely utilized device for optical field modulation. However, it is commonly plagued by the significant zero-order beam in the output diffraction pattern.

MODIFIED GRAVITY EMERGING FROM THERMODYNAMICS AND HOLOGRAPHIC PRINCIPLE [PDF]

open access: yes, 2010
A new conception is proposed in [E. P. Verlinde, arXiv:1001.0785 [hep-th] and [T. Padmanabhan, Mod. Phys. Lett. A25 (2010) 1129] that gravity is one kind of entropic force.

PRINCIPLES OF HOLOGRAPHIC TECHNOLOGIES

open access: yes, 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.
