Pre-holography

open access: yesPhysical Review D, 2008
We construct a symplectic isomorphism, h, from classical Klein Gordon solutions of mass m on (d+1)-dimensional Lorentzian Anti de Sitter space (equipped with the usual symplectic form) to a certain symplectic space of functions on its conformal boundary (only) for all integer and half-integer Delta (= d/2 + (1/2)(d^2 + 4m^2)^{1/2}).

From Single to Multi‐Material 3D Printing of Glass‐Ceramics for Micro‐Optics

open access: yesSmall Methods, EarlyView.
This article explores advancements in two‐photon lithography (TPL) for fabricating high‐refractive‐index micro‐optics. It examines single and multi‐material 3D architectures in glass and ceramics (GLACEs), highlighting photoresin customization, critical fabrication conditions, and cross‐scale structural and optical characterization.

Cone holography with Neumann boundary conditions and brane-localized gauge fields

open access: yesJournal of High Energy Physics
Cone holography is a codimension-n doubly holographic model, which can be interpreted as the holographic dual of edge modes on defects. The initial model of cone holography is based on mixed boundary conditions. This paper formulates cone holography with

In‐Situ Monitoring the Magnetotransport Signature of Topological Transitions in a Chiral Magnet

open access: yesSmall Methods, EarlyView.
The connection between magnetotransport and high‐resolution magnetic imaging is established by simultaneously monitoring magnetotransport properties and conducting in‐situ Lorentz Transmission Electron Microscopy. Ex‐situ approaches necessitated separate specimens, resulting in ambiguous correlations due to sample differences.

Dislocation Introduction via Domain Engineering in Mg2Sn Single Crystal to Improve its Thermoelectric Properties

open access: yesSmall Methods, EarlyView.
This study proposed domain engineering and point‐defect control for developing high‐performance thermoelectric materials. Mg vacancies and dislocations introduced into Mg2Sn single crystals enhanced thermoelectric performance through decoupling carrier‐phonon transport.
