Impact-induced mixing generated the stratified soils of the Lunar South Pole Aitken Basin

Communications Earth & Environment
The Mg-pyroxene annulus in the South Pole–Aitken (SPA) basin holds crucial information about the lunar crustal evolution, yet its mineralogy and origin remain debate. Here we analyzed the mineralogy, exogenic ejecta, and soil evolution of the 2.8-billion-

Observing non-Hermiticity induced chirality breaking in a synthetic Hall ladder

Light: Science & Applications
Non-Hermitian topological photonics plays a key role in bridging topological matter with gain and loss engineering in optics. Here we report the experimental observation of the break of chiral currents in a Hall ladder from the non-Hermiticity by ...
