Monodromic transparency of axion domain walls
Journal of High Energy PhysicsWe revisit the study of light interacting with QCD axion domain walls from the perspective of the non-linear axion coupling to photons, g a F F ~ $$ g(a)F\overset{\sim }{F} $$ , which encodes the effects related to the breaking of the axion shift ...

, 2007 The understanding of the Universe at the largest and smallest scales traditionally has been the subject of cosmology and particle physics, respectively. Studying the evolution of the Universe connects today's large scales with the tiny scales in the very

Gauguin's questions in particle physics: Where are we coming from? What are we? Where are we going?
, 2007 Within particle physics itself, Gauguin's questions may be interpreted as: P1 - What is the status of the Standard Model? P2 - What physics may lie beyond the Standard Model? P3 - What is the `Theory of Everything'?

A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Baryogenesis via QCD preheating with nonadiabatic baryon chemical potential
Journal of High Energy PhysicsThe chiral phase transition in QCD can be supercooled in the thermal history of the universe to be instantaneously out-of equilibrium, if QCD is coupled to a dark QCD sector exhibiting the dark chiral phase transition of the first order. In that case the

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Aspects of the cosmology of right-handed sneutrinos without lepton-number violation [PDF]
, 2008 In this work we add a Dirac right-handed neutrino superfield to the Minimal Supersymmetric Standard Model (MSSM). We discuss the interactions of the right- handed (RH) sneutrino and its mixing with its left-handed counterpart. We study the possibility of

Advanced Engineering Materials, EarlyView.Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Symmetries and selection rules: optimising axion haloscopes for Gravitational Wave searches
Journal of High Energy PhysicsIn the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. We demonstrate that the response is largely dictated by the symmetries of the
