Prediction of a layer nonlinear Hall effect in bilayer nonmagnetic or antiferromagnetic systems
Zehou Li, Shenda He, Pan Zhou +3
Nonlinear Hall effects provide a powerful probe of quantum geometry in solids and enable rectification phenomena beyond the constraints of linear response. In this Letter, we predi…

Measurement of the double Dalitz decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
The BESIII experiment measured the rare decay of the eta meson into two electron-positron pairs, determining its branching fraction to be about 2.6 × 10⁻⁵.

Observation of Polarization and Determination of Its Electric and Magnetic Moments in
BESIII Collaboration, M. Ablikim, M. N. Achasov +703
The BESIII experiment observed the polarization of the hyperon Ξ(1530)^0 in ψ(3686)→Ξ(1530)^0 anti‑Ξ(1530)^0 decays and measured its electric and magnetic multipole moments via ang…
