Modern Physics Letters A, 2008 We perform the first study of baryons in holographic QCD with [Formula: see text] multi-D-brane system in type IIA superstring theory. The baryon is described as a chiral soliton solution in the four-dimensional meson effective action derived from holographic QCD.

Journal of High Energy PhysicsAbstract We show how to encode the radiative degrees of freedom in 4-dimensional asymptotically AdS spacetimes, using the boundary Cotton and stress tensors. Background radiation leads to a reduction of the asymptotic symmetry group, in contrast to asymptotically flat spacetimes, where a non-vanishing news tensor does not restrict ...

Numerical heterodyne holography with two-dimensional photodetector arrays [PDF]
Optics Letters 25, 10 (2000) 716, 2011 We present an original heterodyne holography method for digital holography that relies on two-dimensional heterodyne detection to record the phase and the amplitude of a f ield. The technique has been tested on objects as much as 13 mm in size. Consistency checks were performed, and high-resolution images were computed.

Singularity development and supersymmetry in holography [PDF]
, 2017 We study the effects of supersymmetry on singularity development scenario in holography presented in \cite{Bosch:2017ccw} (BBL). We argue that the singularity persists in a supersymmetric extension of the BBL model. The challenge remains to find a string theory embedding of the singularity mechanism.

Recent Advances in Dielectric Chiral Metasurfaces
Advanced Physics Research, EarlyView.This review article mainly focuses on the recent advances in dielectric chiral metasurfaces, which exhibit remarkable optical chirality. Many new physical conceptions will be introduced during the fast development of the dielectric chiral metasurfaces, such as chiral quasi‐BIC, chiral guided modes, and nonlocal metasurfaces.

Additives in Biphasic Hydroformylation: An Analysis of the Influence of the Interfacial Area
Chemie Ingenieur Technik, EarlyView.Optimizing homogeneous biphasic hydroformylation offers significant potential for improving chemical efficiency by use of additives or by investigating different stirrer and reactor designs. Traditionally, efforts have focused on conversion rates and selectivity, but advanced techniques such as high‐pressure borescopy now allow detailed in‐situ ...

Journal of Biophotonics, EarlyView.This study presents a compact monocular VO that captures high‐frame‐rate retinal videos of the ONH during flicker light stimulation. The device demonstrated its ability to detect flicker‐induced changes in retinal parameters related to blood flow in healthy subjects, providing insights into temporal and spatial retinal variations.

Experimental Observation of Quantum Holographic Imaging [PDF]
, 2013 We report the first experimental observation of quantum holographic imaging with entangled photon pairs, generated in a spontaneous parametric down-conversion process. The signal photons play both roles of "object wave" and "reference wave" in holography but are recorded by a point detector providing only encoding information, while the idler photons ...
