Holographic M5 branes in AdS 7 × S 4
Journal of High Energy Physics, 2021 We study classical M5 brane solutions in the probe limit in the AdS 7 × S 4 background geometry that preserve the minimal amount of supersymmetry. These solutions describe the holography of codimension-2 defects in the 6d boundary dual N $$ \mathcal{N} $$

Ultrafast volume holography for stretchable photonic structures
Optics Express, 2019 Stretchability and flexibility are two key requirements for manipulating the propagation of light in compact and high-performance lab-on-a-chip systems. These requirements are best met by embedding stretchable and flexible tuning elements such as volume phase gratings (VPGs) in polydimethylsiloxane (PDMS), making them attractive alternatives to ...

Wavefront Line‐Scan Imaging Via a Single‐Pixel Detector
Advanced Science, EarlyView.We propose and demonstrate a wavefront line‐scan imaging paradigm that integrates 1D spatial light modulation with single‐pixel detection. Benefiting from 1D modulation, not only is the imaging speed improved, but also the storage of modulation patterns is reduced by several orders of magnitude.

Impedance of Nonelectroneutral Solid Electrolyte Interphases With Nanopores: A Theoretical Model
Advanced Science, EarlyView.Physical modeling reveals that often‐neglected non‐electroneutrality and nanopores in the solid‐electrolyte interphase (SEI) govern the impedance behavior. Under nonreactive conditions, the low‐frequency constant‐phase element (CPE) phenomenon can be attributed to the nonelectroneutral local conditions in the SEI.

Extreme‐Thickness Meta‐Membrane for Controlling Terahertz Vectorial Beams
Advanced Science, EarlyView.We propose ultra‐thin (λ/30) transmissive terahertz metasurfaces combining near‐field resonant and detour phases in coupled‐slit meta‐atoms, enabling continuous phase and polarization control beyond conventional designs. Based on leaky‐mode theory, scalar and vectorial terahertz Bessel beams at 0.39 THz are experimentally demonstrated, with ...

HOLLOWGRAPHY DRIVEN HOLOGRAPHY: BLACK HOLE WITH VANISHING VOLUME INTERIOR [PDF]
International Journal of Modern Physics D, 2010 Hawking–Bekenstein entropy formula seems to tell us that no quantum degrees of freedom can reside in the interior of a black hole. We suggest that this is a consequence of the fact that the volume of any interior sphere of finite surface area simply vanishes. Obviously, this is not the case in general relativity.

A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS
Advanced Electronic Materials, EarlyView.A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.
