Laser &Photonics Reviews, Volume 19, Issue 3, February 5, 2025.Femtosecond laser irradiation inside Al2O3‐SiO2 and ZrO2‐Al2O3‐SiO2 glasses can induce polarization‐controlled birefringent nanostructures, along with local precipitation of refractory nanocrystals like tetragonal ZrO2 or mullite. These structures yield a persisting positive index contrast with extraordinary thermal stability (>1600 °C), opening a ...Imane Ktafi, Jing Kong, Maxime Cavillon, Bertrand Poumellec, Maureen Yembele, Renaud Valois, Mathieu Allix, Gang‐Ding Peng, Matthieu Lancry +8 morewiley +1 more sourceIon‐Mediated Tearing and Kink Instabilities in the Earth's Magnetosphere: Hybrid‐Vlasov Simulations
Journal of Geophysical Research: Space Physics, Volume 130, Issue 1, January 2025.Abstract
We explore the three‐dimensional structure of ion‐kinetic instabilities in a thin current layer using a hybrid‐Vlasov simulation of the Earth's magnetosphere. The simulation shows the simultaneous growth of tearing and kinking instabilities, which develop in the Sun‐Earth and dawn‐dusk directions, respectively, within the magnetotail current ...I.
