Comments on Noncommutative Open String Theory: V-duality and Holography [PDF]

, 2000
In this paper we study the interplay of electric and magnetic backgrounds in determining the decoupling limit of coincident D-branes towards a noncommutative Yang-Mills (NCYM) or open string (NCOS) theory. No decoupling limit has been found for NCYM with

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

Advanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Holography and Eternal Inflation

, 2004
We show that eternal inflation is compatible with holography. In particular, we emphasize that if a region is asymptotically de Sitter in the future, holographic arguments by themselves place no bound on the number of past e-foldings.

Four-dimensional dynamic flow measurement by holographic particle image velocimetry [PDF]

, 2005
The ultimate goal of holographic particle image velocimetry (HPIV) is to provide space- and time-resolved measurement of complex flows. Recent new understanding of holographic imaging of small particles, pertaining to intrinsic aberration and noise in ...

Multifunctional Programmable Transmissive Metasurface with Phase and Amplitude Manipulation Capability

Advanced Science, EarlyView.
This work provides a multifunctional programmable transmissive metasurface with phase and amplitude manipulation capability in the sub‐6G band. By applying different coding strategies, the proposed metasurface can realize vortex beam generation, holographic imaging under phase coding mode, and multi‐beam forming in phase‐amplitude joint coding mode ...

Holographic complexity and volume

Journal of High Energy Physics, 2018
The previously proposed “Complexity=Volume” or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black holes is removed if the volume is measured in units of the maximal time from

Complexity of warped conformal field theory

European Physical Journal C: Particles and Fields, 2023
Warped conformal field theories in two dimensions are exotic nonlocal, Lorentz violating field theories characterized by Virasoro–Kac–Moody symmetries and have attracted a lot of attention as candidate boundary duals to warped AdS $$_3$$ 3 spacetimes ...

Polarization‐Dependent 3D Holography Generated by Inverse Design Nanoprinting Metasurface

Advanced Science, EarlyView.
A novel polarization‐dependent 3D holography is proposed by introducing polarization as an additional freedom, enabling enhanced depth selectivity and greater control over holographic reconstruction. The efforts perfectly combine the polarization and 3D holography display into ADAM gradient descent algorithm, the application of nanoprinting further ...
