Braneworld Baryogenesis and QCD-Era Magnetogenesis: A Predictive Link

Michaël Sarrazin

We demonstrate that primordial magnetic fields (PMF) play a decisive role in the braneworld baryogenesis scenario of [Phys. Rev. D , 023520 (2024)], where C/CP violat…

Euclid: The convective-transition gap of 47 Tuc

M. Libralato, M. Griggio, R. Gerasimov +140

We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…

Carleman estimates for the Korteweg-de Vries equation with piecewise constant main coefficient

Cristóbal Loyola

In this article, we investigate observability-related properties of the Korteweg-de Vries equation with a discontinuous main coefficient, coupled by suitable interface conditions.…

A framework for continuous superradiant laser operation via sequential transport of atoms

Jana El Badawi, Marion Delehaye, Bruno Bellomo

We perform a theoretical study of a continuous superradiant laser supporting its experimental realization at FEMTO-ST using two sequentially-emitting ensembles of ${}^{171}\mathrm{…
