EDITORS' SUGGESTION
Two-dimensional interacting electrons with nontrivial quantum geometry can spontaneously form honeycomb-lattice crystals that exhibit the quantum anomalous Hall effect.

EDITORS' SUGGESTION
D-TRILEX calculations unveil details of the crossover region in Mott transitions between the weakly and strongly correlated regimes for a half-filled 2D Hubbard model.

EDITORS' SUGGESTION
A new measurement of the cross section from the CMD-3 experiment points to a larger hadronic contribution to muon than previous such measurements, which, if confirmed, would ease the tension between theory and experiment for that magnetic moment.

EDITORS' SUGGESTION
In a system where a standard antiferromagnet coexists with a second, ordered phase, which breaks the sublattice rotational symmetry spontaneously, altermagnetism may emerge as an electronic instability.

EDITORS' SUGGESTION
Interatomic Coulombic decay is experimentally observed in a doubly excited atom despite its extremely short lifetime.
