Glaphene: A Hybridization of 2D Silica Glass and Graphene

Advanced Materials, EarlyView.
‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

Big Bang in dipole cosmology

European Physical Journal C: Particles and Fields
We continue the study of dipole cosmology framework put forward in Krishnan et al. (JCAP 07:020, 2023), a beyond FLRW setting that has a preferred direction in the metric which may be associated with a cosmological tilt, a cosmic dipole.

All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets

Advanced Materials, EarlyView.
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...

Introduction to high-energy gamma-ray astronomy

Comptes Rendus. Physique, 2015
The present issue is the first of of a two-volume review devoted to gamma-ray astronomy above 100 MeV which has witnessed considerable progress over the last 20 years. The motivations for research in this area are explained, the follow-on articles of these two thematic issues are introduced and a brief history of the field is given.

Ruddlesden–Popper Defects Act as a Free Surface: Role in Formation and Photophysical Properties of CsPbI3

Advanced Materials, EarlyView.
This work investigates Ruddlesden–Popper (RP) defects in vapor‐deposited CsPbI3 thin films using electron microscopy, density functional theory, and optoelectronic measurements. The atomic positions at the planar defect are found comparable to those of a free surface, revealing their role in phase stabilization.

A T-duality of non-supersymmetric heterotic strings and an implication for Topological Modular Forms

Journal of High Energy Physics
Motivated by recent developments connecting non-supersymmetric heterotic string theory to the theory of Topological Modular Forms (TMF), we show that the worldsheet theory with central charge (17, 3 2 $$ \frac{3}{2} $$ ) obtained by fibering the (E 8)1 ×

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

Advanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Unveiling regions in multi-scale Feynman integrals using singularities and power geometry

European Physical Journal C: Particles and Fields, 2019
We introduce a novel approach for solving the problem of identifying regions in the framework of Method of Regions by considering singularities and the associated Landau equations given a multi-scale Feynman diagram.

Rare‐Earth Ion Intercalation in Graphene via Thermal and Electrostatic Control

Advanced Materials, EarlyView.
Europium ions reversibly intercalate into the van der Waals gap of bilayer graphene when heat and electrostatic gate act together, switching the stacking order and electronic response on demand. Real‐time transport, simulations, and device tests expose a hidden 2D Eu sheet and its temperature‐tuned diffusion, showing a versatile electrochemical route ...
