Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

Advanced Functional Materials, EarlyView.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Multi-Messenger Connection in High-Energy Neutrino Astronomy

Universe
Low fluxes of astrophysical neutrinos at TeV energies, and the overwhelming background of atmospheric neutrinos below that, render the current paradigm of neutrino astronomy a severely statistics-limited one.

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3

Advanced Functional Materials, EarlyView.
Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...

Corrected calculation for the non-local solution to the g − 2 anomaly and novel results in non-local QED

Journal of High Energy Physics
We provide the corrected calculation of the (g − 2) μ in non-local QED previously done in the literature. In specific, we show the proper technique for calculating loops in non-local QED and use it to find the form factors F 1(q 2) and F 2(q 2) in non ...

On the KKLT goldstino

Journal of High Energy Physics, 2018
We construct general asymptotically Klebanov-Strassler solutions of a five dimensional SU(2) × SU(2) × ℤ 2 × ℤ 2R truncation of IIB supergravity on T 1,1, that break supersymmetry.

Tests of CPT invariance in gravitational waves with LIGO-Virgo catalog GWTC-1

European Physical Journal C: Particles and Fields, 2020
A discovery of gravitational waves from binary black holes raises a possibility that measurements of them can provide strict tests of CPT invariance in gravitational waves.

Focus on High Energy Particle Astronomy

New Journal of Physics, 2009
Astrophysics as a sub-discipline provides both unique opportunities and unique challenges relative to other fields of physics. On the one hand, the scope of astrophysics is literally universal, and we are free to examine the most interesting and exotic phenomena to be found anywhere.

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime

Advanced Functional Materials, EarlyView.
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

Aspects of non-local QED and the weak gravity conjecture

European Physical Journal C: Particles and Fields
We use the weak gravity conjecture (WGC) to investigate the impact of charge dequantization arising from non-local QED on the scale of non-locality of neutrinos. We find this scale to be $$\lesssim 49$$ ≲ 49 TeV as implied by direct bounds and $$\lesssim

Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes

Advanced Functional Materials, EarlyView.
Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.
